  1. Survival estimates obtained via Kaplan-Meier. Hazard ratios obtained via Cox models, with robust sandwich covariance matrix estimates to account for the correlation among multiple events for some subjects. Covariates in adjusted models included age, gender, race, ethnicity, diabetes, hypertension, smoking status, and creatinine level.
