In case of PM10 and Benzoapyrene
this risk was not affected after adjustment for age, gender, COPD,
smoking status, educational level, distance from monitor stations,
season and temperature. In fact, in the multivariate logistic regression
analysis, the OR values were 5.24 (95% CI: 1.52-18.12) for
PM10 and 3.95 (95% CI: 1.06-14.71) for Benzoapyrene exposure in
the month before PE diagnosis (Table 4).
