Table 4. Mean differences in scores of early child development domains using mother's ASQ-3 responses, at child age 12 months (total, n = 1957; intervention, n = 1037; control, n = 920). All outcomes are analysed on cluster-level.

	Intervention (clusters, n = 16)	Control (clusters, n = 16)	Crude intervention-control difference (95% CI); P-value^b	Adjusted intervention-control difference (95% CI); P-value^b
	Mean outcome (95% CI)		Crude intervention-control difference (95% CI); P-value^b
Communication	43.05 (41.18 to 44.91)	33.61 (31.34 to 35.88)	9.43 (6.62 to 12.25); <0.001	7.44 (3.95 to 9.73); <0.001
Gross motor	43.94 (41.69 to 46.20)	36.47 (34.24 to 38.70)	7.47 (4.43 to 10.50); <0.001	5.51 (2.71 to 8.29); <0.001
Fine motor	47.39 (45.07 to 49.70)	43.30 (40.95 to 45.65)	4.09 (0.93to 7.25); 0.013	2.84 (0.32 to 5.37); 0.029

Data are mean of scores in each development domain (95% CI) on the ASQ-3 mother responses. The analysis is adjusted for clustering and controlled for several covariates (sex of the child, child weight at registration, child height at registration, child age at registration and endline, maternal age, maternal education, number of additional children the mother has, number of additional children aged <5 years, and family structure) by logistic regression analysis.
ASQ-3 = Ages and Stages Questionnaire-3. CI = confidence interval.
