Table 2 Leptin levels (geometric mean and 95% confidence levels) and leptin normalized to body mass index (mean + SD) in pre-eclampsia/ pregnancy induced hypertension (PE/PIH) and normal pregnancy by genotype

From: LEPR c.668A>G polymorphism in a cohort of Sri Lankan women with pre-eclampsia / pregnancy induced hypertension: a case control study
