Data are n/N (%) and RR (95% CI). Overall interaction terms were not significant for cooperation rates in all subgroups: gender, p=0.066; age, p=0.72; education, p=0.27; location, p=0.18.
*P values obtained from an interaction term between intervention groups and demographic characteristic.
RR, risk ratio; UGX, Ugandan Shilling.
