Table 2. Multivariate analysis of factors associated with poor short-term outcomes (peak creatinine or renal replacement therapy).

In model 1, linear regression analysis included underlying diabetes, Klotho score, and initial creatinine level; logistic regression analysis included underlying hypertension, Klotho score, and initial creatinine. Model 2 was analyzed as model 1, with the exception that initial creatinine level was excluded.

Variables with a p value less than 0.2 in the univariate analysis were included in a ^alinear or ^blogistic regression analysis using backward elimination.
