The geographical distribution of leukemia 69 soldiers of the German army died of leukemia between 1957 and 1970. Investigations were made with regard to their geographical distribution, in comparison to 1500 healthy soldiers. The percentage of leukemia patients, who lived in rural areas (villages up to 500 inhabitants) was 2.1 times higher. With regard to the birth-place this "rural provenance" was even more significant (3.6 times higher). This means: every fifth soldier, who died of leukemia, originated from a little village (of the control-group: every sixteenth). A local incidence ("clusters") was not found. The professions were of no particular significance. These findings raise the question if there exist risk factors in rural environment (domestic animals?).
1957年至1970年间，69名德国军队士兵死于白血病。对他们的地理分布进行了调查，并与1500名健康士兵进行了比较。居住在农村地区（人口不超过500人的村庄）的白血病患者比例高出2.1倍。就出生地而言，这种“农村出身”更为显著（高出3.6倍）。这意味着：每五名死于白血病的士兵中就有一名来自小村庄（对照组中：每十六名中有一名）。未发现局部发病率（“聚集性”）。职业没有特别的意义。这些发现提出了一个问题，即农村环境中是否存在风险因素（家畜？）
