CI, confidence interval; DAA, direct-acting antiviral; eGFR, estimated glomerular filtration rate.
eGFR improvement was defined by ≥10% increase in eGFR from baseline to post-treatment average in the 12 months after completing DAA therapy. The multivariable model includes demographics and predictors with P < 0.1 in the univariate model. Only nondiabetic status and baseline eGFR < 60 ml/min per 1.73 m2 predicted improvement in eGFR after DAAs in multivariable models.
