Cigar and pipe smoking and myocardial infarction in young men.
Article in British medical journal (Clinical research ed.), 1987. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The effect of cigar and pipe smoking on the risk of myocardial infarction was evaluated in an interview study of 572 men with non-fatal first myocardial infarctions and 934 hospital controls. The study was conducted in the north eastern United States from 1980 to 1983. All subjects were 40-54 years of age, and none had smoked cigarettes for at least two years. Among men who had never smoked cigarettes the relative risk of myocardial infarction for those who smoked at least five cigars a day, compared with not smoking cigars and pipes and allowing for other risk factors, was estimated to be 1.7 (95% confidence interval 0.6 to 4.8). Among ex-smokers of cigarettes the corresponding estimate for those who smoked at least five cigars a day was 4.5 (2.2 to 9.2). The estimates for men who smoked fewer cigars, or pipes, were closer to 1.0 and not significant. Men who stop smoking cigarettes and switch to at least five cigars a day apparently continue to have an increased risk of myocardial infarction, possibly because they continue to inhale the smoke.
