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

introductionThis study aimed to investigate which of the STONE, Clinical Research Office of the Endourological Society (CROES), stone‒kidney size (SKS), Seoul National University Renal Stone Complexity (S-ReSC) and Guy’s nephrolithometry scores are more effective in predicting stone-free rates and postoperative outcomes after percutaneous nephrolithotomy (PCNL) in obese patients.

methodsThe study data were retrospectively obtained from the electronic medical records of obese patients (body mass index (BMI) > 30 kg/m2) who underwent PCNL at a single center between February 2022 and July 2025. The data were evaluated in accordance with the Declaration of Helsinki with ethics committee approval. Patients were examined in two groups: a residual fragment group and a stone-free group.

resultsA total of 295 patients were included; 205 were stone free, whereas 90 had residual stone fragments. The long axis length, surface area, volume, and proportion of staghorn stones were significantly greater in the residual fragment group (P < 0.001). Guy’s and SKS scores were significantly greater in the residual fragment group, whereas the CROES score was significantly greater in the stone-free group. No significant differences were observed for the STONE or S-ReSC scores. In receiver operating characteristic (ROC) analysis, the CROES score demonstrated 80% sensitivity and 67% specificity at a cutoff value of 195. The sensitivities of the Guy’s and SKS scores were 87% and 83%, respectively, with specificities of 47%. In multivariate analysis, the CROES score, stone long axis, and Guy’s score were identified as independent predictors of residual stone fragments. Postoperative complications were also evaluated, although no scoring system demonstrated a significant ability to predict complications.

conclusionOur data reveal that the CROES provides the most accurate estimate of stone-free success in obese individuals.
