Suppose a group of researchers conducted a randomized controlled trial to determine if a safe sex intervention helped prevent chlamydia among college students. In total, 220 college students participated in the randomized controlled trial, of whom 106 were randomized to the intervention condition and 114 to the control condition. Participants in the intervention condition were offered an online educational module on safe sex practices. Participants in the control condition did not receive any specific resources on safe sex practices. After one year, the participants were asked to report if they had chlamydia at any point during follow-up. The data from this study are summarized in table 1.   Table 1.
