MIF and Abnormal renal physiology: Normalization of urine MIF levels to urine creatinine did not meaningfully impact the observed kinetics: the urine MIF/creatinine ratio seemed higher in patients without renal dysfunction on days 0 and 2 with the biggest difference in the medians (and IQRs) between patients with and without renal dysfunction on day 2: 0.29 (0.16–0.87) pg/μmol and 0.65 (0.28–1.88) pg/μmol.
