Erratum to: Long-term exposure to fine particulate matter and incidence of type 2 diabetes mellitus in a cohort study: effects of total and traffic-specific air pollution.

Unfortunately, the original version of this article [1] contained an error. The paragraph of the results starting with “The relative risks…” contained errors in the reported effect estimates and confidence intervals.

The paragraph read:

The relative risks from the unadjusted crude model and for the main model are shown in Table 2. When expressing RRs per IQR, exposure to total PM10 was related to an increase in type 2 diabetes incidence of 20 % (RR of 1.20, 95 %-CI: 1.01;1.31) in the main model. The corresponding RR for PM2.5 was 1.11 (95 %-CI: 0.99;1.23). For traffic-specific PM, the estimates for this measure of population distribution of exposures were similar with a RR of 1.11 (95 %-CI: 0.99;1.17) for PM10TRA and a RR of 1.10 (0.99;1.23) for PM2.5TRA.

But it should have read:

The relative risks from the unadjusted crude model and for the main model are shown in Table 2. When expressing RRs per IQR, exposure to total PM10 was related to an increase in type 2 diabetes incidence of 20 % (RR of 1.20, 95 %-CI: 1.01;1.42) in the main model. The corresponding RR for PM2.5 was 1.08 (95 %-CI: 0.89;1.29). For traffic- specific PM, the estimates for this measure of population distribution of exposures were similar with a RR of 1.11 (95 %-CI: 0.99;1.23) for PM10TRA and a RR of 1.10 (0.99;1.23) for PM2.5TRA.
