To examine the association between tea drinking and the risk of lung cancer in Chinese population.
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.
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).
Tea drinking might serve as a protective factor on lung cancer in the Chinese population.
研究饮茶与中国人群肺癌风险之间的关联。
检索中文和英文文献数据库中所有相关的已发表文章，并进行荟萃分析。计算合并比值比（OR）和95%置信区间（CI），以评估饮茶与肺癌风险之间的关联及剂量反应关系。
共纳入12项研究。与不饮茶者相比，饮茶者患肺癌的风险呈负相关（OR = 0.66，95%CI：0.49 - 0.89）。
饮茶可能是中国人群肺癌的一个保护因素。
