Relationships between fasting prolactin concentrations, IHTG, VLDL-TG, and fasting DNL. Spearman correlation analyses of associations between fasting prolactin concentrations and intrahepatic-TG (IHTG, panel A, lactating and formula group sample sizes n = 18 and 9, respectively), VLDL-TG concentration (panel B, n = 18 and 9), and fasting fractional de novo lipogenesis (DNL percent, panel C, n = 17 and 10). DNL, de novo lipogenesis; IHTG, intrahepatic triacylglycerol.
