Evaluating Serum Galectin-9 Diagnostic Value

Check if the same lab product or an alternative is used in the 5 most similar protocols
To assess the difference and correlation between a set of nonparametric data, the Kruskal‒Wallis test followed by Dunn’s multiple comparison test was performed, except when analysing keratinization, where the Mann–Whitney U-test was used. Additionally, correlation analyses were performed using Spearman’s rank correlation coefficient. All statistical analyses were performed using Prism 5 software (GraphPad software, La Jolla, CA, USA). p ≤ 0.05 was considered significant. To determine the diagnostic value of serum galectin-9 to discriminate between controls, LSIL, HSIL and CC patients, receiver operating characteristic (ROC) curves were generated using SPSS statistical software version 26 (IBM; Armonk, NY, USA).

A two-way ANOVA was used to analyze histopathology scores, colonic cytokine gene expression, colonic cytokine levels, and serum cytokine levels with stressor exposure (HCC, FWD, and RST) and sex (male vs. female) as the between subject’s variables. Statistical outliers were removed from the data set based on the criteria of greater than two standard deviations from the mean. An alpha level of p < 0.05 was set as the rejection criteria for the null hypothesis. All data were analyzed using SPSS statistical software version 26 (IBM Corp, Armonk, NY, USA).

Temporal Effects of Exercise on Plasma Biomarkers

Check if the same lab product or an alternative is used in the 5 most similar protocols
All statistical analyses were carried out with SPSS statistical software version 26 (IBM Japan, Tokyo, Japan). The average value and standard deviation were calculated for all measures.
Elapsed time (within conditions) and the presence or absence of acute exercise (between conditions) were factors for investigating the temporal effects of exercise on the plasma Hcy concentration, blood non-mercaptoalbumin/mercaptoalbumin ratio, plasma vitamin B2 concentration, and plasma folic acid concentration. A two-way analysis of variance (ANOVA) was performed using repeated measurements. If a significant difference was found in the inter-condition comparison, a paired t-test or Wilcoxon signed-rank test was performed to identify the cause of the significant difference. If a significant difference was found in the intra-conditional comparison, a one-way ANOVA or Friedman test by repeated measurement was performed. All tests were two-sided, and the significance level was set at P = 0.05.

Cultural Factors and Neuropsychological Profiles

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analyses were performed using IBM SPSS Statistical Software (Version 26). Pearson partial correlations controlling for age, were used to associate cultural factors and left hemisphere MRI volumetric and the raw scores from the neuropsychological measures. Only left hemisphere structures were included in the analyses since the neuropsychological tests examined were heavily language based, and also to reduce error variance by reducing the number of variables examined in this study.
Multiple linear regression analyses were applied with age, acculturation, and literacy as predictor variables, and the neuropsychological raw scores and left hemisphere neuroimaging scores as the dependent variables

Eating Disorder Demographics in Clinical Trials

Check if the same lab product or an alternative is used in the 5 most similar protocols
In this cross-sectional study, we collected age, sex, race, ethnicity, and primary diagnosis data from ClinicalTrials.gov for completed interventional studies with results (including children and/or adults) from January 1, 2011, to January 1, 2021, using the term eating disorder. The search was conducted on September 5, 2021. We excluded studies conducted outside the United States. Race and ethnicity categories were prespecified by ClinicalTrials.gov.1 (link) Primary diagnoses were classified as anorexia nervosa (AN), bulimia nervosa (BN), BED, and other. Per the Common Rule, this study did not require institutional review board approval, as it was based on publicly available information. We followed Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline for cross-sectional studies and used SPSS statistical software version 26 (IBM Corp) for descriptive analyses.

Statistical analyses were performed using the IBM SPSS Statistical software version 26 (SPSS, Inc, Chicago, IL). A P < 0.05 was considered statistically significant. The demographic and clinical characteristics of patients with and without delirium were compared. Categorical variables are described as frequencies and percentiles. Continuous variables, such as age, are described as mean ± standard deviation. The analysis of specific risk factors associated with delirium was carried out using univariate analysis. Differences in categorical variables were tested by the Chi-square or the Mid-P exact tests, in accordance with the size of the cells. The Mann–Whitney U-test, or the Student t-test, was used to compare continuous data depending on the data distribution.
The study was approved by the Helsinki Committee of the Soroka Medical Center (SOR-0047-19) and the Ministry of Health Committee (Form 8, Request #201911315, dated November 4, 2019).

Investigating Intervention Outcomes through Statistical Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical tests were conducted using the SPSS statistical software version 26 (IBM). Baseline demographic data were presented using count numbers and percentages. The outcomes for each group were presented in terms of mean and SE. The generalized estimating equation was adopted to identify the between-group, within-group, and interaction effects between time and group. The exchangeable working correlation matrix was used to emphasize the same spacing between repeated measurements for each participant. Intention-to-treat was used for the primary analysis. A result was significant at 2-tailed P < .05. Data were analyzed from May 1 to 10, 2022.
