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

backgroundThis multicenter international cross-sectional observational study characterized vascular and valvular calcification burden and correlations with pulse pressure, diabetes, hypertension, and cardiovascular diseases in prevalent hemodialysis patients.

methodsWe enrolled 275 consecutive adults with end-stage renal disease on maintenance hemodialysis for ⩾3 months. Coprimary endpoints were prevalences of: (1) echocardiographic calcification in mitral valve, aortic valve or mitral annulus; (2) aortoiliac tree vascular calcifications by plain lateral lumbar X-ray. Correlations among calcification sites and with demographics and comorbidities were determined. Pulse pressures were determined.

resultsSubjects' mean ± standard deviation (SD) age was 56 ± 15.9 years; mean (SD) dialysis duration was 4.5 ± 4.3 years. Overall, 100% of echocardiographically imaged patients (n = 243) had calcification in aortic valve, mitral valve, or mitral annulus; 77.8% of X-rayed patients (n = 248) had abdominal aortic calcification. Radiographic abdominal aortic calcification score correlated significantly with calcification of aortic valve (p < 0.0001) and mitral annulus (p = 0.0001) but not mitral valve. Aortic valve, mitral valve, and mitral annulus calcification correlated significantly among themselves (p < 0.0001). Moderate/severe aortic valve calcification was significantly more prevalent in patients aged ⩾65 years than <65 years, men than women, and Whites than African Americans. Pulse pressure correlated significantly with vascular calcification score (p = 0.0049) but not with valvular calcification at any site.

conclusionsVascular and valvular calcification are highly prevalent in the hemodialysis population. Peripheral vascular calcification correlates significantly with elevated pulse pressure and can be assessed easily using lateral lumbar X-ray. Further studies investigating the interaction between pulse pressure and development or progression of vascular calcification are of interest.
