Difference and 95%CI in probability of comorbid conditions between age groups (reference group: 0–44 years) among lung cancer patients in urban China. a shows the difference in predicted probability (95% CI) of comorbidities between age groups (reference group: 0–44 years) among lung cancer patients in urban China. b shows the difference in predicted number (95% CI) of comorbidities between age groups (reference group: 0–44 years) among lung cancer patients in urban China. c shows the difference in predicted probability (95% CI) of having other malignancy between age groups (reference group: 0–44 years) among lung cancer patients in urban China. d shows the difference in predicted probability (95% CI) of having hypertension between age groups (reference group: 0–44 years) among lung cancer patients in urban China. e shows the difference in predicted probability (95% CI) of having pulmonary disease between age groups (reference group: 0–44 years) among lung cancer patients in urban China. f shows the difference in predicted probability (95% CI) of having diabetes mellitus between age groups (reference group: 0–44 years) among lung cancer patients in urban China. g shows the difference in predicted probability (95% CI) of having cardiovascular disease between age groups (reference group: 0–44 years) among lung cancer patients in urban China. h shows the difference in predicted probability (95% CI) of having liver disease between age groups (reference group: 0–44 years) among lung cancer patients in urban China
