Table 4. Primary outcome comparisons between and within groups by percentile subgroups (PP population)

Variable	Percentile subgroups	Changed from baseline
		CG	p*	EG	p*	p**
Height (cm)	< 3rd%	2.74 ± 0.77 (n = 9)	< 0.0013)	3.62 ± 0.93 (n = 9)	0.0084)	0.0441)
	3rd – 10th%	3.00 ± 0.82 (n = 20)	< 0.0013)	4.26 ± 1.91 (n = 11)	0.0034)	0.0122)

p-values were compared within each group.
p-values were compared between groups.
p-values were derived from independent t-test.
p-values were derived from Mann-Whitney U test.
p-values were derived from paired t-test.
p-values were derived from Wilcoxon’s signed rank test.
PP, per-protocol; CG, control group; EG, experimental group.
