Agent | Crude percentage (Unadjusted) | Odds ratio (pandemic era vs. prepandemic era; adjusted as below) | ||||
---|---|---|---|---|---|---|
Prepandemic | Pandemic | Model 1 (unadjusted) | Model 2 (+ patient factors) | Model 3 (+ center-level variation) | Model 4 (sensitivity analysis) | |
Lymphocyte-depleting agents | 73.2% | 67.8% | 0.720.770.82 | 0.650.700.74 | 0.400.530.69 | 0.400.520.69 |
Maintenance steroids | 69.1% | 69.3% | 0.951.011.08 | 0.850.900.97 | 0.901.362.07 | 0.911.462.35 |
Model 1 was unadjusted. Model 2 included various recipient factors (age, race, sex, previous history of transplant, body mass index, diabetes, hypertension, primary cause of end-stage renal disease, time on dialysis, serum albumin, previous history of malignancy, previous history of peripheral vascular diseases, primary insurance, hepatitis C virus, and cytomegalovirus), donor factors (deceased vs. living, age, race, sex, body mass index, serum creatinine, hepatitis C virus, cytomegalovirus; for deceased donors – donation after circulatory death, diabetes, hypertension, stroke as the cause of donor death, pulsatile perfusion, and cold ischemic time; and for living donors – biologically related donor), and HLA-A/B/DR matching. Model 3 (main analysis) also adjusted for center-level variation by including random intercepts and random slopes. Model 4 was a sensitivity analysis restricted to 172 (72.3%) transplant centers that performed more than 3 recipients during the pandemic era.
