Table 5 Post hoc power analysis of subscales of Intelligence and Development Scales (IDS).A post-hoc power analysis of overall cognitive development revealed a high statistical power (0.99).

Input: Effect size f(V)	0.29	Output: Noncentrality parameter λ	64.16
α err prob	0.01	Critical F	2.59
Total sample size	219	Numerator df	8
Number of groups	2	Denominator df	210
Response variables	8	β	0.99
		Pillai V	0.05
η ((8×7.73)/(8×7.73+210)=0.22)) was used to calculate the effect size, i.e., f(V)=0.22/(1–0.22)=0.29.
