Associations between long-term fine particulate matter exposure and hospital procedures in heart failure patients
Fig 1
Associations between annual average PM2.5 and hospital procedures among heart failure patients.
Shown here are associations between annual average PM2.5 and the three Bonferroni significant procedures. Significance was determined according to the primary analysis approach (quasi-Poisson). We also show the percent change and 95% confidence interval associated with the sensitivity analysis for the Poisson Mixed-Effects model (which included a random intercept for zip code) and Zero-Inflated Poisson model (which included all individuals as opposed to just those with at least 1 procedure). See Methods for complete description of all analysis approaches. Percent change and 95% confidence interval presented per 1 μg/m3 increase in PM2.5. Gly Hemoglobin = Glycosylated Hemoglobin Test; Prothrombin = Prothrombin Time Test.
