Serum Leptin Levels by Group^*

Serum Leptin Values	Control Group (N = 30)	SCFE Group (N = 40)	P Value
Mean†	5.9 ± 7.3 (0.4 to 24.4)	14.9 ± 11.1 (0.4 to 53.5)	<0.001
Median‡	2.4 (1.0 to 10.4)	13.0 (6.3 to 20.4)	<0.001

^*Patients with SCFE were shown to have higher mean and median serum leptin levels compared with control patients.

^†The values are given as the mean and the standard deviation, with the range in parentheses, in nanograms per milliliter.

^‡The values are given as the median, with the IQR in parentheses, in nanograms per milliliter. As leptin data were nonparametric, the median and the IQR are the preferred descriptors (the mean leptin level was included for completeness).
