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
backgroundThis study compared the safety and efficacy of endoscopic combined intrarenal surgery (ECIRS) and minimally invasive percutaneous nephrolithotomy (mPCNL) in the treatment of solitary kidney calculi.
methodsA retrospective analysis was conducted on patients with solitary kidneys and complex renal calculi treated at our center between July 2021 and December 2024.
resultsTwenty-eight patients underwent ECIRS, and thirty underwent mPCNL. The median operative time was significantly shorter in the mPCNL group (P<0.05), while postoperative hospital stay, drainage duration, and hemoglobin reduction were comparable between groups. The 3-month stone-free rate (SFR) was significantly higher in the ECIRS group (89.30% vs. 66.70%, P = 0.039); multivariate analysis identified surgical approach and stone volume as independent predictors of 3-month SFR. Postoperative day 1 Scr was significantly lower in the ECIRS group (P = 0.001), with surgical approach predicting immediate Scr. Overall complication rates (21.43% vs. 33.33%) showed no difference (P>0.05).
conclusionCompared with mPCNL, ECIRS provides significantly higher 3‑month SFR and better perioperative renal protection in patients with solitary kidney calculi, despite longer operative time. Complication rates are comparable between the two modalities. Therefore, ECIRS represents a safe and effective minimally invasive option for complex solitary kidney stones.
