The flowchart of patient enrollment. We extracted demographic data, diagnoses, and contact information from 1611 patients with kidney diseases, whose kidney biopsies were performed from January 2017 to December 2019. We telephoned 1287 of them with available phone numbers from April 15 to 25. After excluding refusals and death, we reached 1190 patients in the end. We excluded 26 dialysis patients and included 1164 patients for analysis of follow-up conditions.
