Summary of model comparison for predictions.

Columns from left to right: (1) Outcomes. nsCAI = condomless anal intercourse with non-steady partners, STI = sexually transmitted infection, nsP = sex with non-steady partners. (2) P value of likelihood ratio test (pLRT) of univariable model with behavioural clusters vs. null model. (3) pLRT of multivariable model including age, last nsCAI or nsP status, prior syphilis (or number of prior syphilis episodes for count outcomes) as predictor variables vs. the same model plus behavioural clusters. (4 through 9) Akaike information criteria (AIC), Bayesian information criteria (BIC), and area under the receiver operator characteristic curve (auROC) for multivariable model including age, last nsCAI or nsP status, prior syphilis (or number of prior syphilis episodes for count outcomes) as predictor variables and of the same model plus behavioural clusters. Clusters included in the models were inferred based on long-term nsCAI patterns for the top half of the table or long-term nsP patterns for the bottom half of the table. Green shading means a better performance for the model with clusters.
