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

Coronary microvascular dysfunction is present in the majority of patients with acute coronary syndromes, myocardial infarction with nonobstructive coronary arteries, and takotsubo syndrome. Assessment of the coronary microcirculation via a noninvasive index of coronary microvascular resistance (CMVR) based on coronary angiography is currently employed by many laboratories (AngioMVR). A proposal is presented herein of a new index of CMVR, based on the duration of the transient ECG repolarization changes during coronary angiography (ECGMVR), well known to occur in patients with and without coronary artery disease, and specific for the left and right coronary artery contrast injections, which have been widely documented, starting 60 years ago. It will be imperative for the index of ECGMVR to be correlated with the currently implemented AngioMVR and the TIMI frame count index, for the validation of the ECGMVR.
