Mechanisms of Chronotropic Incompetence in Heart Failure With Preserved Ejection Fraction.
Article in Circulation. Heart failure, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02524145 (Determinants of Chronotropic Incompetence in Patients With Heart Failure and a Preserved Ejection Fraction), which is not on this map.

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.
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.

Abstract
backgroundChronotropic incompetence is common in heart failure with preserved ejection fraction (HFpEF) and is associated with impaired aerobic capacity. We investigated the integrity of cardiac β-receptor responsiveness, an important mechanism involved in exertional increases in HR, in HFpEF and control subjects.
methodsThirteen carefully screened patients with HFpEF and 13 senior controls underwent exercise testing and graded isoproterenol infusion to quantify cardiac β-receptor-mediated HR responses. To limit autonomic neural influences on heart rate (HR) during isoproterenol, dexmedetomidine and glycopyrrolate were given. Isoproterenol doses were increased incrementally until HR increased by 30 beats per minute. Plasma levels of isoproterenol at each increment were measured by liquid chromatography with electrochemical detection and plotted against HR.
resultsPeak VO
conclusionsContrary to our hypothesis, patients with HFpEF displayed impaired cardiac β-receptor sensitivity compared with senior controls. In the 7 out of 13 patients with HFpEF with age-appropriate β-receptor sensitivity, peak HR remained low, suggesting impaired sinus node β-receptor function may not fully account for low exercise HR response. Rather in some patients with HFpEF, chronotropic incompetence might reflect premature cessation of exercise before maximal sinus node activation.
