Mean differences and standard deviation of in cognitive scores based on ECD before 24 months and malnutrition (HAZ and WAZ) at 2 years of age

	TONI scores mean (±sd)	P value	Verbal scores mean (±sd)	P value	Coding scores mean (±sd)	P values
ECD	N = 111		N = 131		N = 97
High	82.5 (9.0)		5.0 (3.0)		5.3 (3.3)
Low	86.9 (8.7)	0.010	6.2 (3.3)	0.038	6.8 (3.7)	0.027
HAZ	N = 105		N = 119		N = 89
≤ −1.00	82.2 (7.2)		5.0 (3.2)		4.4 (3.5)
> −1.00	85.9 (10.1)	0.043	5.9 (3.2)	0.108	6.6 (3.3)	0.004
WAZ	N = 106		N = 120		N = 90
≤ −1.00	81.8 (7.6)		4.5 (3.2)		4.5 (3.4)
> −1.00	86.3 (9.8)	0.015	6.2 (3.0)	0.005	6.6 (3.4)	0.005

ECD = early childhood diarrhea; HAZ = height-for-age z score; TONI = Test of Nonverbal Intelligence; WAZ = weight-for-age z score.
