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

Given the large amount of myocardium supplied by the left anterior descending (LAD) artery, it understandably receives additional scrutiny during coronary angiography. However, these same features make the interpretation of pressure wire physiology more nuanced to avoid overtreatment. This review provides case examples to underpin an extensive literature review supporting the argument that a "positive" fractional flow reserve (FFR) in the LAD needs to be approached with caution. A large hyperemic gradient, or low FFR, can arise from either a severe and focal lesion in conjunction with low flow or diffuse disease coupled with intact or normal flow. Separating these two scenarios, and the wide continuum between them, ultimately requires upstream assessment of absolute myocardial perfusion, although a pressure wire pullback can help identify diffuse patterns unsuitable for revascularization.
