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

backgroundsHeart rate (HR) and stroke volume (SV)-the components of cardiac output-have a complementary relationship. Poor HR increase during exercise is associated with poor exercise tolerance in heart failure (HF) with preserved ejection fraction (HFpEF), but its prognostic impact remains unclear. Furthermore, whether the compensation for poor HR increase with SV during exercise is associated with prognosis remains unknown.

methodsWe evaluated 129 consecutive hospitalized HF patients with sinus rhythm and left ventricular ejection fractions > 40% who underwent cardiopulmonary exercise testing before discharge from the index hospitalization.

resultsPatients (age: 66 [55-74] years; 73% male) were divided into four groups by median HR reserve (HRR; peak-rest HR: 34 bpm) and O

conclusionThe overlap of lower increases in HR and O
