Notes: Numbers present the p-values obtained from joint tests of equality of means of the socioeconomic characteristics detailed in Table 1 across different groups of youths from the RCT. Column 1 test differences in socioeconomic characteristics between youths randomly selected for the phone survey with those who were not-selected. Column 2 analyzes differences between those youths randomly selected to be part of the survey who responded to it with those who were selected but did not respond. Column 3 compares characteristics of youths who responded to the survey with those who were not selected to participate on the survey.
