Average associations from random‐effects meta‐analysis between ECCE participation and being off track in early childhood development, by country income group

	Child is developmentally off track according to the ECDI
	(1)	(2)	(3)	(4)
	Low‐income	Lower middle‐income	Upper middle‐income	High‐income
Attends ECCE (=1)	0.58 [0.55–0.62]	0.59 [0.56–0.62]	0.71 [0.65–0.76]	0.74 [0.59–0.94]
Number of children	58,744	64,391	47,258	3625
Number of countries	13	22	22	4

Outcome variable in all models is a binary indicator of children being developmentally off track according to the ECDI. Estimated coefficients are odds ratios with 95% CIs in brackets. Country income group estimates were generated using random‐effects meta‐analyses of country‐specific logit model estimates shown in Figures S2–S5.
