Dalager et al.

A hospital-based case–control study examined risks of NHL and Hodgkin’s disease in Vietnam veterans or era veterans seen in VA hospitals in 1969–1985 (Dalager et al., 1991, 1995). Study participants were born in 1937–1954. The number of veterans who had NHL was compared with the number of veterans who had diagnoses other than NHL. Exposure was determined on the basis of having served or not having served in Vietnam or on the basis of surrogates of Agent Orange exposure, including branch of service, combat-duty occupation, or corps.

For the investigation of NHL risk, 201 cases and 358 controls were ascertained. Service in Vietnam was not associated with an increased risk of NHL (OR 1.03, 95% CI 0.70–1.50). In Navy veterans ever in Vietnam, the OR was 0.70 (95% CI 0.31–1.60) for NHL. The 283 Hodgkin’s disease cases were compared with 404 controls; the result was an OR of 1.28 (95% CI 0.94–1.76) for any service in Vietnam. For the
