The association between smoking duration and lung cancer mortality significantly increased after stove improvement with a chimney compared with that before stove improvement (P = 0.002 for interaction between smoking and stove improvement) [21].
When smoking duration was categorised (i.e., <20, ⩾20 <30, ⩾30 <40, and ⩾40 years), a positive and statistically significant trend was observed after stove improvement, whereas no trend was observed before stove improvement (HRinteraction=1.00, 1.26, 1.51, and 1.62, Ptrend=0.005).
