Fig. 3From: Modulation of CYP2E1 metabolic activity in a cohort of confirmed caffeine ingesting pregnant women with preterm offspringScatterplot of the maternal theobromine/caffeine nanomolar ratio against maternal caffeine concentration in nanomole/milliliter, surrogate for the metabolic activity rate of CYP2E1. A distinct positive effect on this metabolic activity rate was seen in those subjects exposed to acetaminophen, compared to the rate of those not exposedBack to article page
