The German Radon Project - Feasibility of Methods and First Results

Lung cancer risk in male workers occupationally exposed to diesel motor emissions in Germany

“…The response rate among eligible cases was 77 percent. Population controls satisfying inclusion criteria (a)±(c) were randomly selected from compulsory registries of residents or by modi®ed random digit dialing [Kreienbrock et al,1992] and were frequency matched to cases on sex, age, and region. The response rate for controls was 41 percent.…”

Histologic types of lung carcinoma and age at onset

“…[21][22][23] Patients with histologically or cytologically confirmed lung carcinoma with primary tumors were recruited from 15 study clinics in this study region. Patients were eligible if 1) they were Ͻ75 years of age, 2) they were resident in the study region, 3) they had lived in Germany for Ͼ25 years, 4) the interviews were conducted within 3 months of diagnosis, 5) they were not too ill, and 6) their tumor type was not "carcinoid."…”

Occupational risk factors for lung cancer among young men

“…It included 1004 cases and the same number of population referents, individually matched for region, gender, and age (+5 years) (12). The other study on lung cancer and indoor radon was conducted by the GSF (GSF National Research Centre for Environment and Health) from 1990 to 1996 (13). It covered parts of Northrhine-Westphalia, Rhineland Palatinate, eastern Bavaria, the Saar region, and Thuringia and Saxony in eastern Germany.…”

“…The inclusion criteria that applied to both the cases and referents were current residence within the study area and an age of less than 75 years (GSF study) or year of birth after 1912 (BIPS study). Further details on both studies have been published elsewhere (7,12,13).…”
