When compared to healthy controls, there is a strong association between the KIT Score and predisposition to kidney injury, even in subjects with normal renal function in CKD 1 (eGFR > 90), with a likelihood ratio of χ12=148.4 (LR p-value < 0.0001) and an assay threshold of 18.5 had a sensitivity and specificity of 92.9 (exact 95% CI: 87.0%, 96.7%) and 94.4% (exact 95% CI: 84.6, 98.8%), respectively. This evidence concerns the gene KIT and chronic kidney disease.
