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

purposeA rising trend involves the application of machine learning to coronary computed tomography angiography (CCTA) for predicting physiological significance of coronary lesions. This study aimed to formulate a clinical model using CCTA-derived features and the least absolute shrinkage and selection operator (LASSO) regression method to predict hemodynamically significant coronary stenosis.

methodsThe study population comprised individuals prospectively recruited from two tertiary medical centres with suspected or known coronary artery disease. The model was developed using patients from Centre 1 and independently validated in patients from Centre 2. All participants underwent CCTA followed by invasive coronary angiography with fractional flow reserve (FFR) measurements. The LASSO model incorporated coronary morphological and plaque features derived semi-automatically from CCTA, along with clinical and demographic variables, as input predictors. Model performance was assessed against the reference standard of invasive FFR ≤ 0.80.

resultsThe analysis included 210 diseased vessels from 133 patients-141 vessels from 84 patients in Centre 1 (development cohort) and 69 vessels from 49 patients in Centre 2 (validation cohort). Using the LASSO algorithm, nine predictive variables were selected from an initial set of 33 candidate features: heart rate, minimal lumen diameter (MLD), area stenosis, diameter stenosis ≥ 50%, lesion length/MLD

conclusionsA prediction model integrating coronary and plaque parameters outperformed existing CCTA-based methods in identifying hemodynamically significant coronary stenosis, offering improved accuracy for ischemia detection.
