  1. Categorical variables are expressed as frequency (%). LTR lung transplant recipient, KTR kidney transplant recipient, SOT solid-organ transplant, HTA hypertension, CVD cardiovascular disease, eGFR estimated glomerular filtration rate, CS Corticosteroids, AZA Azathioprine, MMF Mycophenolate mofetil, FK506 Tacrolimus, CsA Cyclosporin A, Evero Everolimus, ATG anti-thymocyte globulin, OKT3 anti-CD3. ---: data was not available, NA not applicable. Data on induction treatment was missing for two LTR and two KTR. One LTR did not receive any induction treatment.
  2. *Qualitative variables were compared using a Chi-squared test. Significant comparisons are highlighted in bold.
