Attenuation of social class and reproductive risk factor associations for Hodgkin lymphoma due to selection bias in controls.
Cancer Causes Control. 2004; (7): 731-9
Hodgkin lymphoma (HL) risk has been linked with higher social class and lower parity, but our prior population-based case-control study in adult women had unexpected null findings for these variables. Because subject participation was 87% for cases but 65% for random digit-dialing (RDD) controls, we examined representativeness of our controls and the impact of detected bias on prior results.
