We reviewed 8000 medical records of patients with cirrhosis, 23 of whom had a concomitant diagnosis of lymphoma and only 10 met the inclusion criteria for the study. Additionally, we reviewed 658 medical records of patients with lymphoma, of which 620 were possible control candidates, and only 20 were electronically randomized to maintain a 1:2 ratio of cases and controls.
