The study investigators hypothesized that early infection could be associated with worse postoperative outcomes; hence 2 groups were considered: (1) an early hospital-associated SARS-CoV-2 infection group comprising patients who had a positive molecular test result ≤7 days after surgery, with or without symptoms; and (2) a late hospital-associated SARS-CoV-2 infection group comprising patients whosThe Annals of thoracic surgeryS0003-4975(22)00802-5https://www.ebi.ac.uk/biostudies/studies/S-EPMC9174100biostudies-literatureEffect of Hospital-associated SARS-CoV-2 Infections in Cardiac Surgery.
