Plasma SP-D and urinary NGAL levels in septic patients. Plasma SP-D levels in septic patients with AKI KDIGO stage 1, 2, 3 and without AKI (a). Significantly higher plasma SP-D levels were observed in septic AKI stage 1 patients, which were consistent with the severity of kidney injury. Positive correlation between plasma SP-D levels and urinary NGAL levels were showed (b). Pearson analysis shows r = 0.85, 95% CI 0.80–0.89. The area under the ROC curve of plasma SP-D level, urinary NGAL level and SP-D-rs721917 CC genotype to identify the presence of AKI were 0.84, 0.91 and 0.58, respectively (c)
