SMR (*100) and 95% CI of prostate cancer in relation to cadmium exposure in 7 occupational cohort studies.
The summary estimate was obtained using a random-effects model. The dots indicate the SMRs (*100). The size of the shaded square is proportional to the percent weight of each study. The horizontal lines represent 95% CIs. The diamond data marker indicates the summary SMR. CI: confidence interval; SMR: standardized mortality ratio.
