对118名铅接触工人及108名对照组工人的血压研究发现，在血铅为44.26μg／dL时，铅接触工人的收缩压显著高于对照组。分组研究发现，收缩压在组间有剂量-反应关系趋势，在血铅30．20μg／dL，收缩压显著高于对照组。多元逐步回归分析发现，在控制了一些其他影响血压的因素后，铅接触工人的血铅水平与收缩压和舒张压均有剂量-反应关系。
A study of blood pressure in 118 workers exposed to lead and 108 workers in the control group found that when blood lead was 44.26 μg / dL, systolic blood pressure was significantly higher in lead exposed workers than in controls. Group study found that systolic blood pressure in the dose-response relationship between the trend in the blood lead 30.20μg / dL, systolic blood pressure was significantly higher than the control group. Multivariate stepwise regression analysis found that after controlling for some other factors that affect blood pressure, lead levels in lead exposed workers were dose-response dependent both systolic and diastolic blood pressure.
