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 is the leading single cause of preventable death in England and also increases the risk of postoperative complications. The preoperative period is a potential opportunity to introduce smoking cessation interventions to smokers to reduce the risk of postoperative complications. A systematic search was conducted to find all studies that investigated the effectiveness of preoperative smoking cessation interventions. The primary outcome was smoking cessation at surgical time to the last follow-up, and the secondary outcome was postoperative complications that required treatment or ICU admission. A random-effects meta-analysis was used to synthesize the outcomes. Sixteen studies were included in the review (3505 participants), and 14 studies were included in the meta-analysis (2940 randomized participants). The quality of evidence was moderate due to the high risk of bias and heterogeneity. We found that patients who were provided with a smoking cessation intervention had significantly increased odds of quitting smoking by the time of surgery compared with usual care, with a reported relative risk (95% CI) 1.64 (1.30-2.07) and at the longest follow-ups with RR (95% CI) 1.38 (1.12-1.70). Moreover, there was no difference found in the rate of postoperative complications between intervention and control conditions with RR (95% CI) 0.81 (0.62-1.06). The use of standardized outcome measurements is recommended to reduce heterogeneity for future studies, and further investigation focusing on patient perspectives is needed.
