Optimal period of smoking cessation to reduce the incidence of postoperative pulmonary complications in lung cancer.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesPostoperative pulmonary complications (PPCs) provoke an extended hospital stay and increased postoperative mortality. Although several factors can cause PPCs, smoking is the only factor that can be adjusted within a short period of time preoperatively. However, the optimal period of smoking cessation to reduce the risk of PPCs remains unclear.
methodsA total of 1260 patients with primary lung cancer who underwent radical pulmonary resection between January 2010 and December 2021 were analysed retrospectively.
resultsWe classified patients into 2 groups: non-smokers (patients who had never smoked) and smokers (patients who had ever smoked). The frequency of PPCs was 3.3% in non-smokers and 9.7% in smokers. PPCs were significantly less frequent in non-smokers than in smokers (P < 0.001). When smokers were classified according to the duration of smoking cessation, the frequency of PPCs was significantly lower for a duration of 6 weeks or more than for <6 weeks (P < 0.001). In a propensity score analysis performed for 6 or >6 and <6 weeks' smoking cessation in smokers, the frequency of PPCs was significantly lower for smokers with 6 or more weeks' smoking cessation than for smokers with <6 weeks' smoking cessation (P = 0.002). A multivariable analysis identified <6 weeks' smoking cessation as a significant predictor of PPCs for smokers (odds ratio: 4.55, P < 0.001).
conclusionsSmoking cessation for 6 or more weeks preoperatively significantly reduced the frequency of PPCs.
