Clinical features of coronary artery ectasia in the elderly.
Article in Journal of geriatric cardiology : JGC, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the incidence, imaging and clinical characteristics in elderly patients with coronary artery ectasia (CAE).
methodsA retrospective analysis was conducted on patients with CAE who underwent coronary angiography between January 2006 and December 2012. According to age, the enrolled patients were divided into two groups (elderly group, age ≥ 65 years; non-elderly group, age < 65 years). The clinical feature, imaging characteristics and the 5-year survival rate of the two groups were compared.
resultsThe prevalence of CAE in elderly patients was 0.33%. Patients in elderly group were found to have significantly higher proportion of female (30.1% vs. 10.1%, P < 0.001), three-vessel disease (60.5% vs. 45.2%, P = 0.003) and localized ectasia (55.0% vs. 40.2%, P = 0.003). In addition, body mass index (20.90 ± 2.71 kg/m(2) vs. 22.31 ± 2.98 kg/m(2), P < 0.001) and percentage of current smokers (45.0% vs. 64.6%, P < 0.001) were significantly lower in elderly group. Cumulative survival curves demonstrated reduced 5-year cumulative survival at the follow-up in the elderly group compared with the non-elderly group (88.0% vs. 96.0%, P = 0.002). But the 5-year event free survival rate failed to show a significant difference between the two groups (31.0% vs. 35.0%, P = 0.311).
conclusionThe prevalence of CAE in elderly patients was 0.33%, which was about 1/3 of the entire numbers of CAE patients. There were significant differences between the elderly and the non-elderly patients with CAE in terms of coronary artery disease risk factors and coronary artery ectatic characteristics. CAE might be associated with increased mortality risk in the elderly.
