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

Background: Understanding the impact of heart failure (HF) phenotype on peak oxygen uptake (peak Methods: Studies comparing peak Results: After screening 3107 articles, 25 unique studies were included in the analysis for the primary outcome (HFrEF n = 3783; HFpEF n = 3279). Peak Conclusions: Our findings highlight distinct physiological impairments along the oxygen cascade in HFrEF compared with HFpEF, with direct implications for the management and treatment strategies of these HF subtypes.
