Association between air pollution and cardiovascular mortality in China: a systematic review and meta-analysis.

ABSTRACT: Air pollutant levels in many Chinese cities remained significantly higher than the upper limits stated in World Health Organization guidelines. In light of limited evidence in China, we conducted a meta-analysis summarizing the association between acute exposure of air pollution and cardiovascular mortality.

Excess risks (ERs) per 10 μg/m³ increase in PM_2.5, PM₁₀, NO₂, SO₂ and O₃ were evaluated. Subgroup analysis was conducted according to lag patterns (lags 0, 1, 2, 0-1, 0-2 days), gender (male vs. female), temperature (cool vs. warm) and age (< 65 vs. ≥
