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

backgroundSince the 1980s, clinical trial evidence has supported aspirin use in the secondary prevention of cardiovascular disease (CVD).

aimTo explore aspirin use among British men with known CVD in a population-based study.

methodLongitudinal study (British Regional Heart Study), in which subjects have been followed up for cardiovascular morbidity and mortality since 1978-1980. Aspirin use was assessed by questionnaires to study participants in November 1992 (Q92); cardiovascular diagnoses are based on general practice notifications to October 1992. A total of 5751 men aged 52-73 years (87% of survivors) completed questions on aspirin use.

resultsOverall, 547 men (9.5%) were taking aspirin daily, of whom 321 (59%) had documented CVD. Among men with pre-existing disease, 153 out of 345 (44%) men with myocardial infarction, 42 out of 109 (39%) with stroke, and 75 out of 247 (29%) with angina were taking aspirin daily. Among men with angina (54% versus 26%) or myocardial infarction (59% versus 42%), those who had undergone coronary artery bypass surgery (CABG) or angioplasty were more likely to be receiving aspirin. Higher rates of aspirin use were also found in those whose last major event occurred after January 1990 (47% versus 34%). There was no association between aspirin use and social class or region of residence.

conclusionDespite strong evidence of its effectiveness, many patients with established CVD were not receiving aspirin. Daily aspirin treatment was less likely in men with less recent major CVD events and in those who had not received invasive treatment.
