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

Cardiac amyloidosis (CA) is a rare but increasingly recognized cause of restrictive cardiomyopathy. Noninvasive assessment of coronary microvascular dysfunction in CA can facilitate earlier diagnosis and improve disease monitoring. We present a case of light-chain (AL) cardiac amyloidosis manifesting as exertional angina with non-obstructive epicardial coronary arteries, in which contrast adenosine stress echocardiography combined with Doppler-derived coronary flow velocity reserve (CFVR) measurement revealed impaired myocardial perfusion and reduced CFVR. The findings were consistent with cardiac magnetic resonance (CMR) and laboratory results, confirming the diagnosis of CA. This case demonstrates the clinical application of contrast adenosine stress echocardiography as a practical adjunct to advanced imaging modalities for evaluating microvascular dysfunction in CA.
