CST3 and hypertensive disorder: Binary logistic regression of renal recovery revealed that baseline serum cystatin C (OR = 0.446, p = < 0.001), hypertension (OR = 2.321, p = 0.017), serum albumin (OR = 1.953, p = 0.006), and baseline serum creatinine (OR = 1.415, p = 0.030) were the significant predictors of the renal recovery in the studied patients (Table 6).
