The characteristics of study participants at their first visit. All data are presented as n (%), unless otherwise specified. Continuous variables were compared using two-sample t-tests; categorical variables analyzed using Pearson chi-square test or Fisher exact test. P values refer to comparisons between non-adherence and adherence with first clinic appointment. Zip code refers to the number of patients who live in the same neighborhood (zip code), our clinic is located in. M = mean; SD = standard deviation.
*2017 HMO patients, 9 PPO patients.
