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

backgroundHybrid intravascular ultrasound-optical coherence tomography (IVUS-OCT) imaging can integrate both advantages. Optical ultrasonic flow ratio (OUFR) was recently developed for functional assessment.

objectivesThis study aimed to verify the diagnostic performance of OUFR using fractional flow reserve (FFR) as the reference standard.

methodsFrom February 2023 to June 2023, 80 patients (126 vessels) with unstable angina pectoris were assessed with FFR and either hybrid IVUS-OCT or stand-alone IVUS imaging before percutaneous coronary intervention in a prospective series. OUFR based on OCT alone (OUFR

resultsAll 3 computed OUFR indexes achieved high agreement with FFR, with OUFR
