In particular, extent of association exposure and COPD in different populations, as well cigarette smoke, clear. To ascertain we performed metaanalysis. Methods We searched MEDLINE, EMBASE, Latin American Caribbean Literature Health Sciences Database analyzed 15 epidemiologic (11 cross-sectional four case-control) met our criteria. Data were extracted independently by investigators using standardized protocol. Results Overall, people exposed to an odds ratio (OR) 2.44 (95% CI, 1.9-3.33) developing relative those smoke. Biomass was clearly identified both women (OR, 2.73; 95% 2.28-3.28) men 4.30; 1.85-10.01), Asian population 2.31; 1.41-3.78) non-Asian 2.56; 1.71-3.83). This also revealed patients with chronic bronchitis 1.77-3.70) 2.65; 1.75-4.03), smokers 4.39; 1.40-4.66) non-cigarette 2.55; 2.06-3.15). Conclusions Exposure COPD.
