2.9. Statistical Analysis
A total of 51 patients were analyzed, divided into two groups: active (n = 29) and placebo (n = 22). The variables were evaluated (1) at different times (questionnaire domains) and (2) at the time of inclusion (demographic and clinical characteristics). For the purpose of questionnaire analysis, a total of 23 numerical values corresponding to subscales of the FIS-40, PSQI, HADS, and SF-36 outcome measures were used. For each one, two samples collected at different times were analyzed, as shown in the CONSORT chart. For variables describing demographic and clinical characteristics, such as age, BMI, heart rate, and medication use, a total of four numerical and five dichotomous variables obtained at baseline were analyzed. The normality of the data was evaluated for all numerical variables using the Shapiro–Wilk test, and the statistical value W was calculated using the appropriate formula. For all cases, results were considered significant for an alpha value = 0.05, and the
