Radiographic Factors Predict Lateral Humeral Fractures

The Kolmogorov-Smirnov test was used to assess distribution. Patient characteristics and radiologic parameters were compared between patients with versus without LHF using paired Student t tests. Descriptive statistics were calculated as means with standard deviations and ranges. Univariate and multivariate logistic regression analysis with a forward elimination method was performed to evaluate factors related to LHF with a 95% confidence interval. For categorical variables, we recoded them to dummy variables and performed regression analysis. In addition, the Fisher exact test was performed to evaluate the relationship of the LHF and sufficient osteotomy (sufficient group [type A] vs insufficient groups [types B-D]). Intra- and interobserver reliability were evaluated by calculating the intraclass correlation coefficient and Cohen kappa coefficient between the measurements by the 2 surgeons. The data were analyzed using PASW SPSS Version 22.0 (IBM Corp). P values <.05 were defined as significant. Given the retrospective nature of the study, we could not perform a priori sample size analysis. Instead, a post hoc power analysis was done using G*Power Version 3.0.10 (Heinrich-Heine-University).

Age-Related Changes in Surgical Outcomes

The data were analyzed using PASW SPSS, version 22.0 (IBM Inc., Chicago, IL, USA). Descriptive statistics are presented as numbers and percentages according to age groups. The Kolmogorov–Smirnov test was used to assess normal distribution. ANOVA was performed to evaluate the significant difference between all age groups. The differences in parameters between age groups were evaluated via post hoc analysis. The results were reported as means, standard deviations, and 95% CI. p values < 0.05 were defined as significant. Intra- and interobserver reliability were evaluated by three surgeons based on the interclass correlation coefficient between measurements.

Predicting Visual Hallucinations in Patients

Check if the same lab product or an alternative is used in the 5 most similar protocols
We performed statistical analyses using SPSS (PASW) version 22 (SPSS, Chicago, IL). We used univariate logistic regression analyses to compare demographic and clinical characteristics between VH and non-VH groups. We did not correct for multiple comparisons because of the exploratory nature of these univariate analyses. Multivariate logistic regression analysis was used as the main analysis to identify independent predictors of VH. Demographic and clinical variables that were statistically significant in univariate comparisons with a P< 0.05 were included in the regression model. As our sample was comprised of both inpatients and outpatients, we also carried out a multivariate regression model including inpatient status. For all analyses, we checked modeling assumptions, including normality of measures, non-constant variance, and influential points. We assessed for multicollinearity to avoid redundancy in variables, including using variance inflation factors (VIF).

Metabolic Profiles in Schizophrenia Siblings

Check if the same lab product or an alternative is used in the 5 most similar protocols
We performed statistical analyses using SPSS (PASW) version 22 (SPSS, Chicago, IL). We used chi-square tests for categorical variables and ANOVAs for continuous variables to compare demographic and clinical characteristics among patient, sibling and control groups. We used mixed model ANCOVA analyses with contrasts to examine 31P MRS measures with diagnosis as a between-subjects factor, age and gender as covariates, and patient-sibling pairs as a random factor. Age was included as a covariate given the age dependence of NAD metabolite measures previously reported in the literature (Zhu et al., 2015 (link)). Our primary outcome measures were pH, PCr/β-ATP and Pi/β-ATP ratios, and the NAD+/NADH ratio. We also examined phospholipid metabolite ratios, NAD+, and NADH. We carried out exploratory bivariate correlation analyses to examine the relationship of Wisconsin Schizotypy positive and negative factor scores, and SCL-90-R total scores to our primary outcome measures in siblings. All hypothesis tests were two-sided and conducted with a significance level of alpha=0.05.

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.
