Behavioral study had been gathered by way of an organized survey at the standard () and you can end line () administered from the independent taught job gurus have been not working in the brand new intervention. A full definition of effects is roofed on the secondary situation (on line additional appendix dos).
Our very own decide to try proportions computation presumed a suggest from a dozen sex workers each community, a maximum of 800 gender experts and an excellent refusal speed away from 10%. Power calculations had been conducted, just in case an enthusiastic IPV prevalence (earlier in the day one year) from 47% and you will uniform condom explore (early in the day 1 year) of 38% considering first assessments. The power computation was did because of the analysing simulated studies from 800 lady, delivered all over groups playing with empirical data that have a selection into the difference across team-peak size of IPV (15%–25% of one’s complete variation) and you may a narrow list of impression systems (exposure proportion=0.75–0.80). Power computations don’t take into account stratification used in the randomisation otherwise are adjustment getting baseline quantities of the outcomes, just like the correlation throughout the years was not known. Efficiency ideal the trial had >80% ability to choose a risk proportion off 0.77, if your coefficient off anywhere between-people version is anywhere between 0.15 and you can 0.
The key analyses used an altered, individual-level intention-to-treat analysis, evaluating consequences among intercourse professionals inside intervention and you can manage villages during the end range. New statistician carrying out the new analyses is actually blinded to study category allowance. […]
