Long-term exposure to PM2·5 and risk of hospital admission for bone fractures
(A) Scatter plot of the multivariable-adjusted residuals from the standard regression model (not including PM2·5) versus level of exposure to fine particulate matter less than 2·5 μm (PM2·5). Blue line corresponds to zero partial residual value. (B) Spline for the multivariable-adjusted association between PM2·5 exposure and number of hospital admissions of Medicare enrollees per zip code, from 2003 to Horizontal dotted line represents zero effect. (C) Density plot of exposure to PM2·5 in the Medicare analysis. The vertical dotted line in B and C represents the primary annual PM2·5 standard of 12 μg/m3 mandated by the US Environmental Protection Agency.
