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

objectiveSystemic sclerosis (SSc) is characterized by calcification, vasculopathy, and endothelial wall damage, all of which can increase the risk of developing atherosclerosis and cardiovascular disease. The aim of this study was to perform a systematic review and meta-analysis to determine whether the risk of atherosclerosis is increased in SSc patients compared to healthy individuals.

methodsA systematic search was performed to identify studies published in PubMed and the Cochrane database up to May 2010, and recently published abstracts were also reviewed. Two reviewers independently screened articles to identify studies comparing the rate of atherosclerosis in SSc patients to that in healthy controls. The studies utilized one of the following methods: angiography, Doppler ultrasound to assess plaque and carotid intima-media thickness (IMT), computed tomography, magnetic resonance imaging, flow-mediated vasodilation (assessed as the FMD%), the ankle-brachial index, or autopsy. For carotid IMT and FMD% values, we computed a pooled estimate of the summary mean difference and explored predictors of carotid IMT using random-effects meta-regression.

resultsOf the 3,156 articles initially identified, 31 were selected for systematic review. The meta-analysis included 14 studies assessing carotid IMT and 7 assessing brachial artery FMD%. Compared to healthy controls, SSc patients had a higher prevalence of coronary atherosclerosis, peripheral vascular disease, and cerebrovascular calcification. Meta-analysis showed that SSc patients had increased carotid IMT (summary mean difference 0.11 mm, 95% confidence interval [95% CI] 0.05 mm, 0.17 mm; P = 0.0006) and lower FMD% (summary mean difference -3.07%, 95% CI -5.44%, -0.69%; P = 0.01) compared to controls. There was marked heterogeneity between the studies, which was mainly attributable to variations in disease duration and differences in the mean/median age between SSc patients and controls.

conclusionPatients with SSc have an increased risk of atherosclerosis compared to healthy subjects. Further studies should elucidate the mechanism of this increased risk.
