Leptin concentrations for whole and skim human milk at each month of lactation. Values are mean ± SD.

Month of Lactation	Whole Human Milk Leptin (ng/mL)	Skim Human Milk Leptin (ng/mL)	p-Value *
2	0.50 ± 0.16	0.32 ± 0.16	p < 0.0001
5	0.48 ± 0.16	0.26 ± 0.07	p < 0.0001
9	0.56 ± 0.11	0.22 ± 0.03	p < 0.0001
12	0.54 ± 0.14	0.21 ± 0.02	p < 0.0001

* p-values indicate significant differences between whole and skim human milk leptin concentrations at given time points.
