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

backgroundHeart failure (HF) is one of the world leading causes of hospitalization and rehospitalization. Cognitive impairment has been identified as a risk factor for rehospitalization in patients with heart failure. However, previous studies reported mixed results. Therefore, we conducted a systematic review and meta-analysis to assess the association between cognitive impairment and 30-day rehospitalization in patients with HF.

methodWe performed a comprehensive literature search through July 2018 in the databases of MEDLINE and EMBASE. Included studies were cohort studies, case-control studies, cross-sectional studies or randomized controlled trials that compared the risk of 30-day rehospitalization in HF patients with cognitive impairment and those without. We calculated pooled relative risk (RR) with 95% confidence intervals (CI) and I

resultsFive studies with a total of 2,342 participants (1,004 participants had cognitive impairment) were included for meta-analysis. In random-effect model, cognitive impairment significantly increased the risk of 30-day rehospitalization in HF participants (pooled RR=1.63, 95%CI: 1.19-2.24], I

conclusionOur meta-analysis demonstrated that the presence of cognitive impairment is associated with 30-day rehospitalization in patients with HF.
