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

Left main coronary artery (LMCA) stenosis in patients with coronary artery disease (CAD) is associated with a significant increase in cardiac events, and determining its contribution to ischemia is essential. Currently, several noninvasive modalities are available for the ischemic assessment of CAD. In multi-vessel disease, including LMCA disease, the accuracy of myocardial perfusion scintigraphy (MPS) for detecting myocardial ischemia can be poor. Fractional flow reserve from computed tomography (FFR-CT) has emerged as a promising noninvasive modality that can provide functional myocardial ischemia information. Herein, we describe the case of a 50-year-old woman with type 2 diabetes who presented to the hospital due to intermittent chest pain on exertion. Coronary computed tomography angiography showed right coronary artery hypoplasia, 25 % stenosis in the LMCA, and 75 % stenosis in the left anterior descending. FFR-CT identified myocardial ischemia due to LMCA stenosis, but MPS did not. Invasive coronary angiography with conventional fractional flow reserve was mostly consistent with the results of FFR-CT. Learning objective: Fractional flow reserve from computed tomography (FFR-CT), which is a novel noninvasive method, can provide absolute, not relative, functional myocardial ischemia information by applying computational fluid dynamics to coronary computed tomography angiography on a lesion-by-lesion basis. FFR-CT can be extremely useful in detecting patients with left main coronary artery stenosis with right coronary artery hypoplasia.
