Figure 4. Transplacental total bile acid gradients in ICP cases and controls.

Figure 4

Graphs representing the differences in the levels of total bile acids between maternal, umbilical cord artery and vein serum samples from normal (A) (n = 15), untreated ICP (B) (n = 7) and treated ICP (C) (n = 5) pregnancies. Black bars = maternal samples, grey bars = umbilical cord vein samples, white bars = umbilical cord artery samples. * p = <0.05, maternal total bile acid vs. cord artery total bile acid and cord vein total bile acid. ** p = <0.005, maternal total bile acid vs. cord artery total bile acid and cord vein total bile acid. ns = not significant.
