Fig. 2: Tests for selective attrition.

Points show the estimated effect sizes for study drop-outs. Panel 2a shows participants who declined to continue at T1 (N = 484 participants) relative to participants who opted to continue (N = 102 participants). Separate effect sizes are shown for Leavers (N = 169 participants who were continuers, N = 23 participants who were drop-outs) and Remainers (N = 315 participants who were continuers, N = 79 participants who were drop-outs) for effects that were moderated by group. Panel 2b shows participants who completed the interaction (N = 120 participants) relative to those who failed to respond or show among those who opted to continue at T1 (N = 262 participants).
