MIF and alkaline phosphatase measurement: A study performed by our group (Deng et al., 2017) identified MIF as an early predictor for discriminating AP patients who had persistent organ failure (n = 20) from those without (n = 50) and healthy controls (n = 10) with an area under the receiver operating characteristic curve (AUC) of 0.90 (95% confidence interval [CI], 0.81–0.96).
