Key: Table presents summary results of all cohort studies that performed PE; data from the nested case-control study by Albers et al (1982) is not included.

^*= The proportion of cohort study groups with positive findings (i.e. # with ≥ 1 positive findings divided by # of study groups evaluated).

^†= The proportion of cohort studies that reported positive dose-relatedness among those cohort studies that evaluated dose-relatedness.
