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

aimsPatients with heart failure (HF) have a poor prognosis and are categorized by ejection fraction. We performed a meta-analysis to compare baseline characteristics and long-term outcomes of patients with heart failure with reduced (HFrEF), mid-range (HFmrEF), and preserved ejection fraction (HFpEF). METHODS AND

resultsA total of 27 prospective studies were included. Patients with HFpEF were older and had a higher proportion of females, hypertension, diabetes, and insufficient neuroendocrine antagonist treatments, while patients with HFrEF and HFmrEF had a higher prevalence of coronary heart disease and chronic kidney disease. After more than 1-year of follow-up, all-cause mortality was significantly lower in patients with HFmrEF 9388/25 042 (37.49%) than those with HFrEF 39 333/90 023 (43.69%) and HFpEF 24 828/52 492 (47.30%) (p < .001). Cardiovascular mortality was lowest in patients with HFpEF 1130/9904 (11.41%), highest in patients with HFrEF 3419/16 277 (21.07%) mainly coming from HF death and sudden cardiac death, and middle in patients with HFmrEF 699/5171 (13.52%) and the non-cardiovascular mortality was on the contrary. Subgroup analysis showed that in high-risk patients with atrial fibrillation, the all-cause mortality of HFpEF was significantly higher than both HFrEF and HFmrEF (p < .001). HF hospitalization was lowest in patients with HFmrEF 1822/5285 (34.47%), highest in patients with HFrEF 12 607/28 590 (44.10%) and middle in patients with HFpEF 8686/22 763 (38.16%) and the composite of all-cause mortality and HF hospitalization was also observed similar results.

conclusionsIn summary, patients with HFmrEF had the lowest incidence of all-cause mortality and HF hospitalization, while the highest all-cause mortality and HF hospitalization rates were HFpEF and HFrEF patients, respectively.
