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

objectiveTo study the natural course of carotid artery stenosis detected by ultrasonography.

designProspective cohort study. Baseline examination in 1982-3 included ultrasound examination of carotid arteries, measurement of ankle-brachial blood pressure index, and detection of atrial fibrillation by 24 hour ambulatory electrocardiography.

settingMalmö, a city in southern Sweden with 230,000 inhabitants. SUBJECTS: 470 men aged 68 years randomly selected from the population.

main outcome measuresIncidence of stroke and transient ischaemic attack and all cause mortality during 10 years of follow up in relation to carotid stenosis, leg artery disease (ankle-brachial blood pressure index below 0.9), and atrial fibrillation.

resultsFifty men had a stroke; six of these were haemorrhagic. Another 11 had a transient ischaemic attack. Eighteen of the men with carotid stenosis (21.6 events/1000 person years) and 43 of the men with normal carotid arteries (14.8 events/1000 person years) had a stroke or transient ischaemic attack (P = 0.188). Men with atrial fibrillation had an increased rate of cerebrovascular events (36.7/1000 person years (P = 0.048). The highest rate was found in men with asymptomatic disease of the leg arteries (38.6/1000 person years) (P < 0.001). The increased risk of stroke or transient ischaemic attack in this group remained after multivariate analysis (relative risk 2.0; 95% confidence interval 1.1 to 3.7).

conclusionsIn this cohort carotid stenosis was not associated with an increased risk of stroke. Part of this lack of association was explained by the high mortality from ischaemic heart disease in men with severe stenosis. Twenty seven of the 61 cerebrovascular events, however, occurred in men who had normal carotid arteries, normal ankle pressure, and no atrial fibrillation.
