Study‐specific relative risks (RRs) and 95% confidence intervals (CIs) were estimated using a random‐effects model. Study quality was assessed using the Newcastle–Ottawa scale.</p> </sec> <sec id="jdi12112-sec-0003" sec-type="section"> <title>Results</title> <p>A total of 19 cohort studies were included in the present meta‐analysis. Of these, 14 studies focused on the association between diabetes and lung cancer incidence, and seven studies focused on the association between antidiabetic treatment and lung cancer incidence. Compared with non‐diabetic individuals, diabetic patients do not have an increased risk of lung cancer (RR = 1.04, 95% CI 0.87–1.24). The association between diabetes and lung cancer remained not statistically significant in subgroup analysis stratified by study characteristics, study quality, diabetes ascertainment or important confounders. A null association between insulin or biguanides therapy and lung cancer risk was found. However, the diabetic patients receiving thiazolidinedione (TZD) treatment had a 20% reduced risk of lung cancer than those without TZD treatment.</p> </sec> <sec id="jdi12112-sec-0004" sec-type="section"> <title>Conclusions</title> <p>No association between diabetes and lung cancer risk was found.
