Data analysis
REGRESSION, SECONDARY
Participant characteristics and feasibility metrics for both treatment and control groups as well as program adherence for the treatment group only were summarized using descriptive statistics. Fisher exact tests examined baseline differences between groups for categorical variables. Percentages were calculated to determine the proportion of participants in each group who reached clinical significance.Both intent-to-treat and per-protocol analysis were conducted. Adjusted ANOVA was used to determine the differences between and within groups in the primary and secondary outcomes at 4 weeks and after the intervention. Multiple comparisons (i.e., post hoc) were adjusted using Bonferonni corrections. Multiple multivariate logistic regression was used to examine determinants of response to intervention. Responders were defined as individuals with a reduction of 80 points or more on the IBS-SSS (Fisher exact tests were used to determine whether the proportion of individuals falling in each intention category differed between treatment and control groups at baseline and postintervention separately and if any changes in proportions of intentions between baseline and postintervention. In the treatment group alone, regression analysis was used to determine whether intention predicts total yoga practice in minutes and whether there was a relationship between total practice minutes and change (baseline to week 8) in IBS-SSS. All analysis was conducted using RStudio version 1.4.1717 using R version 4.1.1.This study has been approved by the Conjoint Health Research Ethics Board (REB ID 20-0084).
