Score statistics for type 3 GEE analysis.
All p values are unadjusted for multiple hypothesis tests. The primary hypothesis is for the interaction of survey and treatment group along with the ORs for screening at follow-up vs. baseline for each treatment group, and other p values may be considered exploratory.
