B, unstandardized coefficients; β, standardized coefficients; CI, confidence interval. The relationship between weight changes (independent variable) and AHI change (dependent variable) was assessed in (1) unadjusted (univariate) regression models and (2) adjusted (multivariable) regression models for the effects of confounders (identified in Supplementary Table S2). AHI and weight changes are both expressed as either absolute change (∆) and percent change (%∆) in the respective models. The adjusted model for absolute AHI change (∆) included baseline BMI and waist circumference, as well as the original study participant, was recruited for (study). The adjusted model for percent AHI change (%∆) included sex, baseline BMI, and waist circumference, as well as study.
