Fig. 1: World map of sample size per country (overlap DNAm and neuroimaging), as covered in MIND.
From: Consortium profile: the methylation, imaging and NeuroDevelopment (MIND) consortium

Sample sizes reflect expected sample size after sample processing (i.e., those featured in Table 1) and additionally include expected sample size for MTWinS (N = 708). Singapore is also included but too small to be shown on the map.
