The role of aortic valve area in the quantitative flow ratio-fractional flow reserve discrepancy in patients with coronary artery disease and severe aortic stenosis.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The accuracy of fractional flow reserve (FFR) and quantitative flow ratio (QFR) in assessing coronary artery disease in severe aortic stenosis (AS) patients may be affected by the severity of AS. Aim: We investigated the relationship between aortic valve area (AVA) and the diagnostic performance of QFR in this context. Material and methods: We analyzed 416 intermediate coronary lesions in 221 severe AS patients using FFR and QFR, categorizing them based on AVA into two groups: AVA < 0.5 cm Results: In all, 47 (21.2%) patients had an AVA < 0.5 cm Conclusions: In severe AS, QFR closely correlates with FFR. However, patients with AVA < 0.5 cm
