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 a known risk for sudden cardiac death (SCD) in the general population. However, its significance in patients with acute coronary syndrome (ACS), a condition that also elevates the risk of SCD, is disputable.

methodsA total of 9704 consecutive ACS patients with available smoking data were included in the analysis. Comprehensive patient data were obtained from the Mass Data in Detection and Prevention of Serious Adverse Events in Cardiovascular Disease research database. A composite endpoint of SCD, SCD aborted by successful resuscitation and accurate implantable cardioverter defibrillator therapy to otherwise potentially fatal ventricular fibrillation/ventricular tachycardia was used. Univariate, age- and sex-adjusted, and a multivariate fine-gray competing risk regression with adjustment to traditional risk factors was conducted.

resultsMedian follow-up time was 6.8 years (IQR, 4.1-10.2), and 454 (4.7%) SCD cases were identified. At the baseline, 23.7% ( N  = 2444) were active smokers, and 20.8% ( N  = 2146) were ex-smokers. In the multivariate model, active smokers had an elevated risk of 1.79 (95% CI, 1.41-2.27; P  < 0.001) for future SCD. Ex-smokers had no elevated risk for SCD in fine-gray subdistribution hazard. Also, active smokers were notably younger (mean age 58.7 years) than non- or ex-smokers (71.1 years and 68.9 years, respectively, P  < 0.001 for both comparisons).

conclusionActive smokers had a 79% higher risk of SCD when compared with nonsmokers. Smoking cessation should be heavily encouraged after ACS. Also, a person's smoking status should be considered in further studies developing SCD and implantable cardioverter defibrillator-benefit risk scores.
