Differences across exposure groups compared using Fisher's exact tests (categorical variables) or Kruskal–Wallis tests (continuous variables).

Includes patients whose first recorded COVID-19 laboratory test positive was within 30 days +/− of transplant. Exposures: demographic and clinical variables abstracted from EMR at the first COVID-19 diagnostic encounter. Outcome: composite all-cause mortality or graft failure within 90 days or 1 year of transplant date. Patients who received transplants within 90 days (Outcome A) or 1 year (Outcome B) of the study end date and those lost to follow-up were excluded.

Legend: Kaplan–Meier analyses, the y-axis represents survivorship, the x-axis represents analysis, time zero was the date of transplant, and composite events were recorded as the date of death or graft failure; patients were right-censored at study end or date of loss to follow-up. CI, confidence interval.

Survival function at 90 days: 0.96, CI: 0.94–0.98.

Survival function at 365 days: 0.94, CI: 0.91–0.96.
