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

backgroundChronotropic incompetence is common in heart failure with preserved ejection fraction (HFpEF) and is linked to impaired aerobic capacity. Whether upstream autonomic signaling pathways responsible for raising exercise heart rate are impaired in HFpEF is unknown. We investigated the integrity of central command and muscle metaboreceptor function, 2 predominant mechanisms responsible for exertional increases in heart rate, in patients with HFpEF and senior controls.

methodsFourteen healthy senior controls (7 men, 7 women) and 20 carefully screened patients with HFpEF (8 men, 12 women) underwent cardiopulmonary exercise testing (peak Vo

resultsPeak Vo

conclusionsCentral command (vagally mediated) and metaboreceptor function (sympathetically mediated) in patients with HFpEF were not different from those in healthy senior controls despite significantly lower peak whole-body exercise heart rates. These results demonstrate key reflex autonomic pathways regulating exercise heart rate responsiveness are intact in HFpEF.
