1 Includes subjects informed after the activity had commenced. 2 Estimators extracted from logistic regression including the corresponding symptom as the dependent variable, and briefing status as the explanatory variable. 3 OR – (95%) CI = odds ratio (uninformed versus informed) – 95% confidence interval. 4 OR – (95%) CI = odds ratio (uninformed versus informed) adjusted for time worked in high- and low-pollution areas -95% confidence interval. | ||||||
