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

backgroundAmong patients with dilated cardiomyopathy (DCM), myocardial inflammation and fibrosis are risk factors for poor clinical outcomes. Here, we investigated the combined prognostic value of these two factors, as evaluated using myocardial biopsy samples.

methodsThis retrospective and multicentre study included patients with DCM-defined as LVEF of ≤45% and left diastolic diameter of >112% of predicted value, without evidence of secondary or ischaemic cardiomyopathy. In myocardial biopsy samples, inflammatory cells were counted using immunohistochemistry, and Masson's Trichrome staining was performed to quantify the myocardial fibrosis as collagen area fraction (CAF). Higher myocardial inflammation was defined as leucocytes of ≥14/mm², including ≤4 monocytes/mm², with CD3

resultsA total of 255 DCM patients were enrolled (average age, 53.1 years; 78% males). Within this cohort, the mean LVEF was 28.0%, mean CAF was 10.7% and median CD3

conclusionsHaving both biopsy-proven higher myocardial inflammation and greater fibrosis predicted the worst clinical prognosis in patients with DCM.
