Fig. 4From: Pharmacokinetic and urinary profiling reveals the prednisolone/cortisol ratio as a valid biomarker for prednisolone administrationHeat map with the relative abundance of urinary steroids and metabolites along in vivo treatments. Within this heat map, urinary relative abundances are presented for the acclimatization period (Blank), growth-promoting treatment (PO1 and IM1), therapeutic treatment (PO2 and IM2), and ACTH treatment. The intensities of each ion were averaged (n = 12) and then log-transformed. Shades of black and white represent, respectively, higher and lower intensities as observed for the different treatmentsBack to article page
