A Meta-Analysis: Air Quality and Lung Cancer Mortality
share
Lung cancer has become one of the most epidemic and fatal malignant neoplasm related diseases for humans in the world. The epidemiological studies conducted over the previous several decades have provided the evidence that exposure to air pollution of particulate matters, such as PM 10 and PM 2.5, over a certain period of time, is associated with elevated mortality. This analysis is going to evaluate how the air quality affect the lung cancer mortality rate with different regional and pollutant matter factors.In this meta-analysis project, our team conducted the analysis gathering 20 studies through Embase, PubMed and Web of Science. Risk ratio (RR) and Hazard ratio (HR) with 95 intervals was used to assess the strength of association between the air quality and mortality of lung cancer.
