[A Meta-analysis on tea drinking and the risk of lung cancer in Chinese population].

OBJECTIVE
To examine the association between tea drinking and the risk of lung cancer in Chinese population.


METHODS
All relevant published articles in Chinese and English literature database were identified. Meta-analysis was conducted. Combined odds ratio (OR) and 95% confidence interval (CI) were calculated to estimate the associations and dose-response relationship between tea drinking and the risk of lung cancer.


RESULTS
Twelve studies were included. An inverse association with lung cancer was observed on tea drinkers when compared to non-tea drinkers (OR = 0.66, 95%CI: 0.49 - 0.89).


CONCLUSION
Tea drinking might serve as a protective factor on lung cancer in the Chinese population.
