The association between air pollution and the daily number of deaths: findings from the Slovak Republic contribution to the APHEA project.

After adjustment for season, temperature and relative humidity, days of week and holidays, secular trends, and autoregressive patterns no significant associations were found between the daily variations in the air pollutants, SO2-24 h and TSP-24 h, and total mortality (RR 0.978, 95% CI 0.96, 0.99; RR 1.008, 95% CI 0.96, 0.99) and cause specific mortality in Bratislava during the study period.
