A representative sample of 254 such men was randomized to be in either the intervention group (n=152) or the control group (n=152). The primary outcome under study getting tested for HIV within the six-months following group assignment (randomization) among those who had been sexually active in this same six-month follow-up period. At six months of follow-up, 141 subjects in the intervention group reported having had sex (with men and/or women) since randomization. Of these 141 men, 114 had been tested for HIV since being randomized. At six months of follow-up, 147 subjects in the control group reported having had sex (with men and/or women) since randomization. Of these 147 men, 40 had been tested for HIV since being randomized. What is the (approximate) estimated relative risk of getting tested for HIV for subjects in the Intervention group compared to subjects in the Control group?
