Fig. 1: Associations of particulate matter air pollutants and risk of incident haematologic cancer subtypes by sex.

Hazard ratios for PM2.5, PM10, and PM10-2.5 are shown in three panels with separate indicators for men (blue) and women (red) with 95% confidence intervals shown as gray lines. Confidence limits that extend beyond the scale are indicated by arrowheads. Units for the HRs: PM2.5 (4.1 µg/m3), PM10 (6.7 µg/m3), and PM10-2.5 (5 µg/m3).
