Environmental risk factors for XXXX .

@entity309 @entity3440
In this review we examine the association between @entity309 ( @entity309 ) and exposure to @entity3440 and other environmental toxicants. We performed a series of meta-analyses of peer-reviewed studies, using 10 studies for @entity3440 , and 5 studies for other exposures published between 1986 and 2001. Before the meta-analyses, all studies were reviewed and evaluated for heterogeneity and publication bias. We detected a significant heterogeneity among studies on @entity3440 and calculated a combined estimator of relative risk (RR), using the random effect model. Most studies reported consistent elevation in the risk of @entity309 with exposure to @entity3440 . The combined RR for @entity3440 exposure was 3.43 195% confidence interval (95% CI) 2.25-5.22] for all studies, and 4.45 (95% CI 2.24-8.86) for male cohorts. The combined RR for male farmers was 1.40 [95% CI 1.18-1.66] and was 1.29 [95% CI 0.84-1.97] for pesticide exposure. The combined RR for hair dressers was 1.52 [95% CI 1.04-2.20]. The findings of this study suggest a significant elevation in the risk of @entity309 from exposure to @entity3440 . Further studies assessing the dose-response effect would greatly aid in determining whether the observed association is causal.
