Rapid loss of vitamin C in a critically ill patient. a The patient’s vitamin C concentrations (black circles) were compared with the critically ill cohort (grey circles) over the 4-day study period. Data for the critically ill cohort represents mean and SD (n = 43). b Increasing C-reactive protein (CRP) concentrations (filled diamonds) relative to decreasing vitamin C concentrations (grey circles). Dotted lines indicate inadequate vitamin C cutoff (50 μmol/L), hypovitaminosis C cutoff (23 μmol/L) and vitamin C deficiency cutoff (11 μmol/L); dashed line indicates infectious disease cutoff for CRP (100 mg/L)
