Figure 2

Frequency histogram plotted as Paracetamol Sulfonation Index (PSI) for clinical phenotyping of SULT vs. number of individuals (n = 36). Abscissa denotes the metabolic ratio expressed as PSI, calculated from unchanged paracetamol and its sulfate and glucuronate conjugates, measured in plasma (A) and urine (B) samples using LC-HRMS, 2 h after ingestion of 1 g of paracetamol. We found a similar distribution of PSI for plasma (A) and urine (B) samples, revealing an identical mean and a right skew. Although the distribution is mostly uniform, individuals with higher sulfonation capacity may be singled out.
