Linear regression models adjusted for pubertal status, gender, educational track, number of sleeping problems and hours of sleep. Caffeine, EDs, and Caffeine and EDs represent the independent dummy-coded variables in which <1 consumption on average per day represents the reference category; self-reported behavioral executive functioning measures are the outcome variables. B, the estimate of increase in self-reported behavioral executive functioning score compared to the reference category; CI, Confidence Interval;
