Stepwise regression used p < 0.1 as entry criteria for single-variable models and retained variables with p < 0.05. Habit variables that did not meet criteria for retention in stepwise model are labeled with a dash (-). Beta coefficients are adjusted for all other covariates in the table and age, gender, randomized group, and stratum
