title: Coffee and tea consumption and risk of lung cancer: a dose-response analysis of observational studies.
abstract: Results from the recent meta-analysis suggested a favorable effect of green tea consumption and risk of lung cancer, while no significant association was found between black tea consumption and risk of lung cancer. Besides, a significantly positive association was found between coffee consumption and risk of lung cancer. However, the relationship of green tea and coffee consumption is unclear. Thus the dose-response relationship was assessed by restricted cubic spline model and multivariate random-effect meta-regression. Results suggested that a linear dose-response relationship exists between coffee consumption and risk of lung cancer, while the dose-response relationship is nonlinear between green tea consumption and risk of lung cancer.
