2.6. Statistical Analysis
One-way analyses of variance tests were used to evaluate the baseline differences between naturally menstruating subjects and those using hormonal contraception. Repeated measures analyses of variance tests were used to analyze the change in BM following supplementation (Cr and PL) and across menstrual phases (FP and LP). Separate univariate analysis of covariance tests were used to assess the difference between treatment groups (Cr and LP) pre- and post-supplementation for TBW, ECF, and ICF, in each MC phase (FP vs. LP), using hydration status (USG) and estrogen concentration as covariates. The significance level was set at ≤0.05. Analyses were completed using SPSS (version 27, IBM, Armonk, NY, USA).
