Sex Differences in Murray Law-Based Quantitative Flow Ratio Among Patients With Intermediate Coronary Lesions.
Article in Journal of the American Heart Association, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
Background The Murray law-based quantitative flow ratio (μQFR) is a novel technique that simulates fractional flow reserve (FFR) from a single angiographic view. However, the impact of sex differences on the diagnostic performance of μQFR has not been investigated. Methods and Results In this study, FFR and μQFR were assessed in 497 intermediate stenoses (30%-70% by visual estimation) from 460 patients (34.3% female). Physiological significance was defined as FFR ≤0.80 or μQFR ≤0.80. After adjusting for potential confounders, female sex was independently associated with higher FFR (
