Association between Particulate Matter Pollution Concentration and Hospital Admissions for Hypertension in Ganzhou, China

Figure 3

Excess risk (ER) and 95% confidence interval (CI) in daily hypertension hospital admission changes in the concentration of gaseous pollutants at different lag days: (a) excess risk (ER) in daily hypertension hospital admissions per 10 μg/m³ increase in SO₂, in single-day lag 56–64 days; (b) excess risk (ER) in daily hypertension hospital admissions per 10 μg/m³ increase in NO₂, in single-day lag 56–64 days; (c) excess risk (ER) in daily hypertension hospital admissions per 10 μg/m³ increase in O₃, in single-day lag 56–64 days; and (d) excess risk (ER) in daily hypertension hospital admissions per 10 mg/m³ increase in CO, in single-day lag 56–64 days.
