Other related information
In all patients, staining of nodular lesions with periodic acid Schiff (PAS), periodic acid methenamine silver (PAM), Masson trichrome, and collagens I, III, IV, V, and VI was performed using frozen section at the time of renal biopsy.
The Cox proportional hazard model was used to calculate the hazard ratio (HR) and 95% confidence interval (CI) for the death-censored endpoint. We investigated the hazard ratio of the difference in staining for the endpoint.
