title: [Association between air particulate matter and stroke attack or mortality: a Meta-analysis].
abstract: OBJECTIVE
  To analyze the associations between particulate air pollution (PM(10), PM(2.5)) and stroke daily attack or mortality.
  
  
  METHODS
  Meta-analysis method was used to polysynthetically analyze 16 quantitative studies about the associations between particulate air pollution and stroke daily attack or mortality. The relative odds ratio (OR)of stroke attack or mortality associated with per 10 µg/m(3) increase of particulate matter concentration was used as effective value, taking a sensitivity analysis for the results.
  
  
  RESULTS
  A 10 µg/m(3) increase in PM(10) was associated with a 1.09% (95%CI: 0.10% - 2.08%) increase in stroke daily attack (OR = 1.011, 95%CI: 1.001 - 1.021) and 0.70% (95%CI: 0.60% - 0.80%) increase in stroke daily mortality (OR = 1.007, 95%CI: 1.006 - 1.008). The results of sensitivity analysis supported above results. As for PM(2.5) OR appeared to be 1.001 (95%CI: 0.992 - 1.010) with a 10 µ g/m(3) increase in stroke daily attack and 1.052 (95%CI: 0.958 - 1.154) for daily mortality.
  
  
  CONCLUSIONS
  There are positive associations between PM(10) and stroke daily attack and mortality, increase of PM(2.5) was not associated with stroke attack and mortality.
