Intracuff Pressure and Postoperative Sore Throat

Check if the same lab product or an alternative is used in the 5 most similar protocols
All statistical analyses were performed using the SAS® statistical package, version 9.4 (SAS Institute, Cary, NC, USA). Data are expressed as the mean ± SD or as frequencies and proportions, as appropriate. The intergroup differences were assessed using Fisher’s exact test and the Mann–Whitney U-test. Possible risk factors for POST were examined by univariate and multivariate analyses. A receiver operating characteristic (ROC) curve was constructed to investigate the cut-off intracuff pressure to correctly predict POST at the maximum area under the curve (AUC), which ranges from 0.5 to 1.0. Spearman’s correlation coefficient was calculated for intracuff pressure ≥ 17 cmH20 at intubation and emergence with cough and hoarseness. A P-value < 0.05 was considered statistically significant.

TSH Levels and All-Cause Mortality

Check if the same lab product or an alternative is used in the 5 most similar protocols
Variables are reported as means (SDs) or as percentages. TSH values were
found to be not normally distributed, therefore we introduced the TSH in the
regression analysis after its log transformation. To test the nonlinearity
relationship between TSH and all-cause mortality, we introduced a quadratic term
of Log (TSH) in the regression analysis. Given the departure from linearity of
the relationship between TSH and all-cause mortality, the cox proportional
hazards models were used to examine the relationship between quartiles of plasma
concentrations of TSH and all-cause mortality over 9 years of follow-up.
Characteristics of subjects were compared across quartiles of plasma
concentrations of TSH using parametric (ANOVA) and non-parametric (Wilcoxon
signed-rank test) test as appropriate. Multivariable Cox proportional hazards
model, adjusted for age, sex and other variables that were significant in the
univariate analyses was used to evaluate the relationship between hormonal
status and mortality. All analyses were performed by the SAS statistical
package, version 9.1 (SAS Institute Inc, Cary, North Carolina) with a type I
error of 0.05

Comparison of Early and Late H. pylori Eradication

Check if the same lab product or an alternative is used in the 5 most similar protocols
Demographic data were expressed as categorical data and mean±standard deviation. The data for categorical variables are presented as percentages. We compared the differences between the early and late H. pylori eradication therapy groups using a chi-square analysis. We calculated the hazard ratios (HR) based on a 95% confidence interval (CI) using a multivariate Cox regression analysis to compare the risk of rehospitalization for complicated recurrent peptic ulcers between the early and late H. pylori eradication therapy groups. A p-value less than 0.05 was considered to indicate a statistically significant relationship. All statistical analyses were performed using the SAS statistical package version 9.2 (SAS Institute, Cary, NC, USA).

Analyzing Income Changes After Industrial Accidents

Check if the same lab product or an alternative is used in the 5 most similar protocols
We used the t-test and analysis of variance (ANOVA) to compare the general characteristics of the study population and the average incomes before industrial accidents according to the industrial classification (manufacturing, construction, or service). A repeated measures ANOVA was used to compare annual differential incomes before and after the industrial accident, as well as the annual income before the industrial accident and the average annual income 5 years after the accident. A paired t-test and repeated measures ANOVA were conducted to compare the income before the accident and the average annual income 5 years later according to the general characteristics of the study population. To investigate the changes in income from before to after the industrial accident according to industry and RTW status, we set the dependent variable as the income minus the income before the accident from the five-year average income and performed a linear mixed model analysis. All statistical analyses were conducted using the SAS statistical package, version 9.4 (SAS Institute, Cary, NC, USA).

Alcohol Treatment Disparities by Race

First, weighted percentages were computed for select participant demographic and psychiatric disorders correlates by race/ethnicity and treatment status. Second, to estimate prevalence ratios (PRs) for the association between alcohol-related treatment and race/ethnicity, we used a multivariable model adjusting for all other sociodemographic factors/psychiatric covariates. Third, to estimate race/ethnicity-stratified PRs for the association between alcohol-related treatment and sociodemographic factors/psychiatric comorbid disorders, we used two multivariable models, one for each race. In a cross-sectional study design, the odds ratio is also referred to as the prevalence odds ratio. Weighted PRs and 95% confidence intervals (CIs) were directly estimated using PROC GENMOD with Poisson distribution for convergence, log link function and estimate statements for all correlates of seeking treatment or help for AUD, adjusting for effects of all other variables (Thompson et al., 1998 (link)). To account for the NESARC-III complex sample design, all analyses presented were generated with PROC SURVEYFREQ and PROC GENMOD using STRATA, CLUSTER, and WEIGHT statements for appropriate variance and standard error estimates. All analyses were conducted with SAS statistical package, version 9.3, (SAS Institute, Inc., Cary, North Carolina).

Evaluating Lactation Responses in Dairy Cows

Check if the same lab product or an alternative is used in the 5 most similar protocols
A replicated (4 × 4) Latin Square experimental design, with four treatments and four periods, was applied. Animals were considered experimental units, they were distributed in the square considering its previous milk yield and parity order. Data were submitted to analysis of variance (ANOVA) and regression (linear and quadratic) using the MIXED procedure and considering animal as random effect in SAS statistical package, version 9.0 (SAS, 2002) . The following causes of variation were evaluated: treatment, period, square, cow within square and the interaction square × treatment. The model applied for ANOVA was: Y ijkl = + Q i + T j + P k + QT ij + A (i)l + e ijk . Where: Y ijkl = mean value obtained for each observation; = general mean of the variable in the experiment; Q i = effect of the square, where i = 1 and 2; T j = effect of treatment j, with j = 1, 2, 3 and 4; P k = effect of period, with k = l, 2, 3 and 4; QT ij = interaction between square i and treatment j; A (i)l = effect of cow l within square i; e ijk = experimental error.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
