The role of haptoglobin in patients with increased CFH concentrations. Haptoglobin concentrations of patients with and without AKI among patients with moderate (A) and high (B) CFH concentrations. Corresponding sensitivity and specificity analysis of haptoglobin concentration for occurrence of AKI within the moderate (A) and high (B) CFH concentration group are indicated. Clinical cutoffs with 90% sensitivity and 90% specificity are indicated. In patients with moderate CFH, n = 16 (12.4%) had haptoglobin concentrations > 2.7 g/l while n = 27 (20.9%) had haptoglobin concentrations < 0.3 g/l. In patients with high CFH, n = 6 (11.5%) had haptoglobin concentrations > 2.4 g/l while n = 21 (40.3%) had haptoglobin concentrations < 0.3 g/l. *P < 0.05
