NA = Not available. This means the authors did not report the information in the manuscripts associated with the studies we reviewed.

a This information was not available whenever authors did not report information for the treatment and comparison groups separately on outcome means, standard deviations, and/or sample sizes.

b Authors reported that the program effect (impact) estimate is statistically significant with a p-value of less than 0.05 based on a two-tailed test.

c For some outcomes, having less of that outcome is favorable. In those cases, an effect with a negative sign is favorable to the treatment group (that is, the treatment group had a more favorable outcome than the comparison group, on average).

d An effect meets the review standards for credible evidence whenever it is statistically significant with a p-value of less than 0.05 based on a two-tailed test, includes the appropriate adjustment for clustering (if applicable), and it is not based on an endogenous subgroup.

Details
Six months after the program ended, the study found no evidence of statistically significant program impacts on the number of times in the past three months the study participants reported having had sex. The study also found no statistically significant program impacts on the proportion of times in the past three months that the young women in the study's sample had sex without using a condom or without using any type of contraceptives.
