Mean Difference in Cognitive z Scores in Children With CM Compared With CC at Enrollment and 6- and 24-Month Follow-ups

Cognitive Area	Enrollment (n = 44)		6 mo (n = 42)		24 mo (n = 38)
	Mean Difference (95% CI)^a	P^b	Mean Difference (95% CI)^a	P^b	Mean Difference (95% CI)^a	P^b
Attention	−0.57 (−1.07 to −0.07)	.020	−0.38 (−0.82 to 0.06)	.090	−0.71 (−1.10 to −0.32)	<.001
Working memory	−1.15 (−1.61 to −0.69)	<.001	−0.31 (−0.67 to 0.05)	.090	−0.28 (−0.69 to 0.13)	.180
Tactile learning	0.82 (0.28 to 1.36)	.0030	0.23 (−0.17 to 0.64)	.250	0.07 (−0.43 to 0.58)	.780

Adjusted for age, gender, nutrition, home environment score, and child’s education levels. Lower scores are worse for attention and working memory; higher scores are worse for tactile learning.
