aDifference between INT and COMP at baseline; bDifference between INT and COMP at final; cn = 1 missing at final in COMP; dSES is measured by ICSEA scores. Quintiles (Q1 = highest, Q5 = lowest) are based on 2011 National data at baseline (cut-offs 940/980/1020/1076/1287) and 2014 National data at final (cut-offs 942/985/1023/1074/1292). The national average ICSEA score is 1000 [31]. NB: As ICSEA score is not an individual-level SES measure but a school-level measure [31], caution should be taken when interpreting these data. Importantly, ICSEA does not use individual information concerning the wealth of the parents or children
