Rho (ρ) is the item-response probability (i.e., probability that recommendation is met at given time point for the given latent class). Rho (ρ)>0.5 indicates high probability of meeting recommendations (<0.5 indicates low probability of meeting recommendations). No covariates were included in this repeated measures latent class model
