Correlations of variables involved in acute kidney injury. Correlations of variables proposed to be involved in the pathogenesis of acute tubular necrosis in malaria associated AKI with marker of renal dysfunction (creatinine) and marker of kidney damage (uNGAL/Ucr). Pearson’s correlation coefficient between plasma P. falciparum histidine rich protein 2 (HRP2) and (A) serum creatinine; and (B) uNGAL/Ucr. Pearson’s correlation coefficient between suPAR and (C) serum creatinine; and (D) uNGAL/Ucr. All variables were log transformed (log₁₀) for correlation plots and Pearson’s analysis. suPAR = soluble urokinase–type plasminogen activator receptor; uNGAL/Ucr = urine neutrophil gelatinase-associated lipocalin corrected for urine creatinine.
