There were 111 participants for T1, defined as 24 to 35 weeks, and 25 completed outside the T1 range. 104 were included for T2 time period, defined as 47 to 65 weeks, and 45 completed outside the T2 range. Of the 111 who completed follow-up at T1, 109 were matched to a control group.1 did not match because their age was missing in their profile, and 1 did not match because sex was missing in their profile. 76 participants completed both T1 and T2 follow-ups.
