Question

A recent case-control study assessed the relationship of hepatitis C virus (HCV) infection to B-cell non-Hodgkin lymphoma (B-NHL). Cases of B-NHL were identified in the hematology department wards of 10 hospitals located in different cities throughout the United States. The control group consisted of non-B-NHL patients admitted to other departments of the same hospitals (e.g. ophthalmology, general surgery, internal medicine, etc). For both cases and controls, only patients with newly diagnosed diseases were included in the study. Testing for HCV was done after cases and controls were hospitalized. Age (years) Cases Controls Number HCV Positive Number HCV Positive <= 55 163 18 231 6 > 55 237 52 165 16
