Figure 3 Associations among gastric emptying time (min), frequency of gastric contractions (mHz), and progesterone levels (ng/mL) in female rats during pregnancy and the estrous cycle. ^aP < 0.03, compared with control (day 0); ^bP < 0.002, compared with days 0 and 20; ^cP < 0.001, compared with day 14; ^dP < 0.001, compared with days 0 and 20; ^eP < 0.05, compared with proestrus; ^fP < 0.001 compared with estrous.
