Fig 2: The Ghrelin/LEAP-2 ratio (Log) in healthy pregnant women at each trimester of gestation and during the follicular and luteal phases of the menstrual cycle (A) and Ghrelin/LEAP-2 ratio during pregnancy in rat (B). A p value of < 0.05 was considered as statistically significant. Mean Log [(Ghrelin ng/mL) × 10)]/Log [(LEAP-2 ng/mL) × 10] were used. Bars with no common letters are significantly different (p < 0.05).
