Analysis of the factors associated with hypertension by logistic regression in coke oven workers

Factors	Hypertension					ECG					IFG					TC
	P Value	OR	OR (95% CI)			P	OR	OR (95% CI)			P Value	OR	OR (95% CI)			P Value	OR	OR (95% CI)
Abbreviations: ECG, electrocardiogram; IFG, impaired fasting glucose; TC, total cholesterol. According to the monitoring results of B[a]P and COEs, the lowest concentration of the coke oven was at bottom, which was considered as B[a]P low-exposure monitoring point and set as the indicator for contrast. While beside and top of the coke oven were considered as B[a]P medium-, high-exposure monitoring point. Compared with B[a]P low-exposure point, P<0.05 was considered have statistical significance.
