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

Introduction: To aim of study was to predict the success rate of the stone composition by visual assessment during endourological procedures, using Fourier transform infrared spectroscopy as a reference standard. Methods: Prospective observational study showed, 150 patients undergoing endourological procedures for urolithiasis between June 2024 and July 2025 were analyzed. The senior consultant, the junior consultant, and the residents visually assessed the stone morpho-constitution (according to Daudon classification) during the endoscopic procedures. Stone samples were obtained which were analyzed using Fourier transform infrared spectroscopy, and the results were correlated with the visual assessment done by the surgeon. Results: Stone analysis by Fourier transform infrared spectroscopy showed 28 (18.67%) of the stones had only one morphological type (pure stones), while 122 (81.33%) had more than one composition of stones (mixed stones). The accurate predictions for pure stones as Uric acid stones and Protein stones, were 43 (84.31%) and 5 (83.33%), respectively, whereas for Calcium Oxalate Monohydrate + Calcium Oxalate Dihydrate (mixed stones) was 126 (79.25%). The overall correct prediction was obtained in 64.44 %. The correct prediction was highest by the senior consultant 110 (73.33%), followed by the junior consultant 97 (64.67%), and the residents 83 (55.33%), respectively. Conclusions: The overall agreement between visual assessment of urinary stone morphology during endo-urological procedures and Fourier transform infrared spectroscopy-based composition analysis in this study was moderate, with a Cohen's kappa value of 0.62.
