Meta-analysis of Implant Survival Rates

Check if the same lab product or an alternative is used in the 5 most similar protocols
Stata MP 14.1 software was applied to process the meta-analysis, randomized model was applied to process the meta-analysis, with heterogeneity indicated by I-square values. To include studies having a 100% implant survival rate, we modified the rates with the formula: [modified survival rate = (number of survived implants − 0.25)/(number of total implants) *100%] in Stata MP 14.1. Considering the data of ISR, MBL and ESBG were based on the 1-year follow-up in majority of the literature, the 1-year post-surgical data of these parameters were considered in the meta-analysis. Moreover, to investigate the clinical reliability of non-grafted TSFE in cases with limited RBH, study on 1-year ISR of non-grafted TSFE was performed among its subgroups with varied RBH values.

Analyzing Intestinal Oocyst Counts in Turkeys

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experimental unit was pooled samples of intestinal contents from turkey groups defined during the analyses of relationships between study variables and severe intestinal lesions (see above, and Tables 2, 3 and 4). Pooled samples were used to analyse the impact of independent variables on OPG counts. OPG was a secondary (continuous) outcome variable. Oocyst counts were log10-transformed. Outcome estimates were reported as median log10 OPG counts.
The distribution of OPG counts within each turkey group was in most cases non-normal (Shapiro-Wilk normality test, swilk procedure in Stata 14.2). OPG data were therefore analysed using non-parametric statistical methods. Kruskal-Wallis rank test (kwallis procedure, Stata/MP 14.2) was used to compare two groups, while Dunn’s test with Bonferroni adjustment (dunntest procedure, Stata/MP 14.2) was used for multiple comparisons. P-values below 0.05 were considered statistically significant.

Analyzing Factors Associated with Skin Cancer

Check if the same lab product or an alternative is used in the 5 most similar protocols
Stata/MP14.1 (Stata Corp. Stata Statistical Software: Release 14) was used for descriptive and inferential analyses. The Shapiro–Wilk test was used to assess normality of distribution. Mean with standard deviation (SD) values were used to present normally distributed data. Chi-square tests were used for analysis of categorical outcomes. The Mann–Whitney U test was performed to compare nonparametric data between groups. Multivariable logistic regression analysis was performed separately to assess factors associated with LR in the BCC and SCC groups. A p-value less than 0.05 was accepted as significant.

Impact of Nursing Visits on Hospice Disenrollment

Check if the same lab product or an alternative is used in the 5 most similar protocols
We performed descriptive statistics and compared cohorts of low (>0 to <3) and high (3+) average nursing visits per week using χ2 tests for categorical variables and Wilcoxon rank sum tests for continuous variables to assess whether there were differences between the groups. Bivariate analyses were conducted to identify variables associated with hospital-related disenrollment. Covariates that were associated with hospital-related disenrollment (P value <.2) were entered into a multivariable logistic regression model and an area under the receiver–operating curve was calculated. Given the use of average number of nursing visits, we performed 2 sensitivity analyses. One excluded patients with a length of stay less than 7 days since these enrollments may have an inflated number of average nursing visits per week that may confound the results (eg, a patient on hospice for 1 day with 1 nursing visit would have an average of 7 nursing visits per week). The second excluded home hospice patients who also received CHC, GIP care, and/or respite care, which indicate an increased intensity of home hospice care that may influence our outcome of interest. We also examined the 2-way interactions between weekly nursing visits and each of the other independent variables. Statistical analysis was conducted using STATA MP 14.1 (College Station, Texas).

Chemsex and Slamsex Epidemiology in MSM

Check if the same lab product or an alternative is used in the 5 most similar protocols
All analyses and data cleaning were conducted in stata/mp 14.1 (StataCorp MP College Station, Texas, USA) and missing data were assumed to be missing at random. The weighted prevalence of chemsex and slamsex in sexually active MSM was calculated overall, and for each chemsex drug, with 95% confidence intervals (CIs). We tested if chemsex and slamsex use differed by various socio‐demographic factors and health indicators using a two‐tailed χ2 statistic, and considered differences to be statistically significant at < 0.05.
We assessed the associations of chemsex and slamsex with UAI, sdUAI, sdUAI with a detectable viral load, and diagnosis with bacterial STIs and hepatitis C using multivariable logistic regression. The associations between chemsex/slamsex and number of casual sexual partners were assessed using multivariable linear regression. All multivariable models were constructed using directed acyclic graphs (Figure S1) to determine which variables to control for 27, 28, 29, 30, 31. All regressions were assessed for statistical significance with an alpha level of 5%.

Statistical analysis of acute versus stable disease

Check if the same lab product or an alternative is used in the 5 most similar protocols
Comparisons between groups were made employing unpaired t-tests and one-way analysis of variance (ANOVA) for normally distributed data or Mann–Whitney and Kruskal–Wallis testing for non-parametric data. Chi-square analyses were used for categorical data. Blood and questionnaire results from acute versus stable disease state were analysed via Pearson correlation coefficients. Time-to-event survival analyses were conducted using Kaplan–Meier methods and log-rank tests. Data are presented as number (percentage), mean±standard deviation (sd) or median (interquartile range, IQR), where appropriate. Statistical significance was accepted at p<0.05. Analyses were conducted on Stata MP 14.1 (Statacorp, Texas, USA).

EGFR TKI Treatment Outcomes

Check if the same lab product or an alternative is used in the 5 most similar protocols
PFS was the primary endpoint. It was defined as the time from EGFR TKI treatment start to progression or death, whichever occurred first, or last follow-up date for patients alive and free from progression at the time of the analysis. OS was a secondary endpoint and was defined as the time from EGFR TKI treatment start to death or last follow-up date for alive patients. Median follow-up (mFU) was calculated according to the reverse Kaplan-Meier technique. PFS and OS curves were estimated by Kaplan-Meier product limit method and compared between the two groups (cases without “other mutations” vs. cases with “other mutations”) by log-rank test. Hazard ratios were estimated by a Cox proportional hazard model adjusted by gender, age (as a continuous variable), smoking habits (current or previous smoker vs. never smoker), and presence of the T790M mutation. Explorative analyses were done to assess the prognostic value of TP53 mutation in this cohort of patients. Statistical analyses were performed using STATA MP 14.1 (StataCorp LP, College Station, TX, USA).

Bayesian Network Meta-Analysis of Treatments

Check if the same lab product or an alternative is used in the 5 most similar protocols
The network meta-analyses will be performed using STATA/MP 14.1 (StataCorp, College Station, TX), through the routine for Bayesian hierarchical random-effects model. The network meta-analysis combines data from several different randomized comparisons across treatments to provide a set of internally consistent estimates, taking into account randomization within each trial. The network meta-analysis will be performed within the framework of a generalized linear model, where the link function specifies the relationship between the outcome and the model coefficients to be estimated. When the endings are continuous, the likelihood is modeled as normal. When the endings are event rates, the likelihood is modeled as Poisson. A random effects model is used for this analysis. Estimation is performed in a Bayesian context using the non-information prior distribution of the parameters. The model is evaluated using the Deviation Information Criterion, a measure that combines model fit and complexity. The analysis is estimated using a Bayesian Markov Chain Monte Carlo model.
