‘Low’ and ‘High’ refer to the levels of corresponding index for collectivisation. The combination of dummy for STI service partnership with government primary healthcare system and levels of collectivisation represent FSWs with a low (or high) level of collectivisation from areas where intervention collaborated (or did not collaborated) with government primary healthcare facilities to deliver STI services.
↵* ORs were adjusted for following background characteristics: current age (entered as continuous variable), any formal schooling (no, yes) marital status (currently married, not currently married), typology of sex work (home-based, street-based, brothel-based) and duration of sex work (entered as continuous variable) using logistic regression.
FSWs, female sex workers; STI, sexually transmitted infections.
