Baseline descriptive statistics of participants with ≥12 months of participation (n = 845), participants with ≥12 months of participation that did not have a follow-up that included lab work at least 12 months after the initial visit (n = 264), participants with ≥12 months of participation and a follow-up reassessment including lab work at least 12 months after the initial visit (n = 581), and the analytic sample which included participants whose nearest follow-up with lab work occurred 12–24 months after the initial visit and had no missing data (n = 144)
