Differences in the physical examination between exposed group and control group
| Items | Exposed Group (n=880) | Controls (n=710) | P Value | ||||
|---|---|---|---|---|---|---|---|
| Cases | Detection Rate (%) | Cases | Detection Rate (%) | ||||
| Workers with SBP of 140 to 159 mm Hg and/or DBP of 90 to 99 mm Hg was defined as stage 1 hypertension. Moreover, SBP of 160 to 179 and over 180 mm Hg and/or DBP of 100 to 109 and over 110 mmHg are defined as stage 2 and stage 3 hypertension, respectively. P<0.05 was considered to be of statistical significance. | |||||||
