Class prevalence among the study sample and adjusted probabilities of responding to each indicator conditional upon membership in the latent class.

*To understand this table’s content, take for instance class 1, which had a prevalence of 18.9%. Conditional upon membership in this class, class 1 respondents had very low adjusted probabilities (close to 0) of responding ‘Yes’ to the first 4 indicators listed and very high adjusted probabilities (close to 1.0) of responding ‘Yes’ to the last two indicators: ‘Has a current chronic medical health problem/pain problem’ and ‘Takes prescribed medication for a medical problem/Receives help for a medical problem, past 30 days’. Based on this pattern of response, class 1 was labeled, for ease of discussion, as ‘use as prescribed’.
