Epidemiological papers that address an association between benzene exposure and non-Hodgkin lymphoma (NHL) were identified and separated by study design. Eighteen studies contained 21 study groups—11 population-based case–control study groups, 3 nested occupation-based case–control study groups and 7 occupational benzene cohort study groups. Petroleum industry studies were not included. Only two of these 21 study groups showed statistically significant associations. However, these were among workers with multiple exposures across industries. Eleven of the 21 study groups presented ratios less than one, two equaled one, and eight were greater than one. Over all, about as many cases were observed (404) as expected (390.0) for an observed to expected ratio of 1.04 (0.94–1.14). After removal of the studies with multiple chemical exposures problems, the observed was 359 cases with 373.2 cases expected, yielding an odds ratio of 0.96 (0.86–1.06). Further assessment of an association with NHL

Epidemiological 向苯暴露和非 Hodgkin lymphoma(NHL) 之间的协会演说的纸被研究设计识别而且分开了。十八项研究包含 21项研究聚集— 11 人口-建立控制学习团体, 3 被筑巢的占有情形–-建立情形–控制研究团体和 7个职业的苯步兵大队研究团体。 石油工业研究不被包括。 只有这 21个研究团体中的二个以统计上来看重要的协会。 然而,这些横过工业是在有多样的暴露工人之中。 21个研究团体中的十一个呈现比少于一, 二等于了一, 和八是大比较一。 在所有的之上, 大约和情形一样多的被观察 (404) 如预期的 (390.0) 为一观察到预期的比 1.04.(0.94 – 1.14)在和多样的化学暴露问题的研究移动之后, 那观察是有 373.2个被期望的情形,屈从的 0.96 的不平等比的 359个情形.(0.86 – 1.06) 和 NHL 的协会进一步的评估应该出自非苯暴露的贡献证明苯暴露和分开。 ? 2005 Elsevier 爱尔兰公司版权所有。
