Note:
1
When covariates were included into the model, latent class membership classification remained almost unchanged with only two cases moved from Class 3 to Classes 1 and 2, respectively.
2
Class 3 (i.e., System-level Barriers Class) was treated as the reference group.
3
Duration of primary drug use was recoded as deviation from overall mean.
