  1. a Conditional response probabilities (0-100) represent the probability of selecting a response option based on a respondent's latent class membership. For example, among the subgroup of respondents who have mild SCD, the probability of selecting "Always" giving up day-to-day household activities or chores is low at 1.4%
  2. b The latent subgroups represent levels of severity for SCD. Respondents who have mild SCD can be interpreted as having a higher probability of selecting a response option related to sparse experiences, such as "Rarely" or "Never". The Moderate subgroup has a slightly probability of selecting "Never" but a higher probability of choosing "Rarely" or "Sometimes". Alternatively, the Severe subgroup have a lower probability of selecting the same response options and a much higher probability of choosing "Usually" or "Always" experiencing SCD
  3. c Unconditional probability. Proportion of sample who fall into each latent class
