1 · What the graph read from 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.

2 · The registry

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

backgroundSmoking cessation is a highly important preparation before thoracic surgery. We examined the effects of short-term smoking cessation intervention before pulmonary resection on postoperative pulmonary complications (PPCs).

methodsA retrospective analysis of prospectively collected data was performed for 753 patients who underwent curative surgical resection for thoracic malignancy at 3 institutions. Patients with a smoking history were instructed to quit smoking. After confirming smoking cessation by at least four weeks before surgery, surgical resection was performed. Subjects were classified into three groups based on their smoking status: abstainers (anyone who had stopped smoking for at least 4 weeks but less than 2 months), former smokers (anyone who had abstained from smoking for more than two months prior to surgery), and never smokers (those who had never smoked). We examined the relationship between the preoperative smoking status and PPCs.

resultsSurgery was performed for 660 primary lung cancers and 93 metastatic lung tumors. The smoking statuses were classified as follows: abstainers (n=105, 14%), former smokers (n=361; 48%) and never smokers (n=287, 38%). The incidence of PPCs among abstainers, former smokers and never smokers was 15%, 8% and 6%, respectively (P=0.01). The mean duration of post-operative chest tube drainage among abstainers, former smokers and never smokers was 3.2, 2.2 and 2.2 days, respectively (P=0.04). The mean post-operative hospital stay among abstainers, former smokers and never smokers was 12.1, 10.6 and 10.2 days, respectively (P=0.07). There was no 30-day mortality in the cohort.

conclusionsShort-term smoking cessation intervention did not enough reduce the PPCs as much as in former or never smokers.
