Therefore, we investigated the incidence of <jats:styled-content style=\"fixed-case\">BL<\/jats:styled-content> in 203,557 solid organ recipients in the U.S. Transplant Cancer Match Study (1987\u20132009) and compared it with the general population using standardized incidence ratios. We also assessed associations with demographic and clinical characteristics, and treatments used to induce therapeutic immunosuppression. <jats:styled-content style=\"fixed-case\">BL<\/jats:styled-content> incidence was 10.8 per 100,000 person\u2010years, representing 23\u2010fold (95% confidence interval (<jats:styled-content style=\"fixed-case\">CI<\/jats:styled-content>) 19\u201328) greater risk than in the general population, and it peaked 3\u20138 years after the time of transplantation.
