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
Objective: To compare the safety and efficacy of four different surgical approaches for the treatment of complex non-hydronephrotic renal stones. Methods: A total of 88 patients with complex non-hydronephrotic renal stones, who underwent surgical treatment at Xiangtan Central Hospital from January 2022 to December 2023, were included in this study. The patients were divided into two groups based on their CT values. Group 1 (CT ≥ 1,000) included 22 patients who underwent puncture-assisted single standard percutaneous nephrolithotomy (PCNL) with a laser for stone fragmentation and retrieval (experimental group), and 12 patients who underwent multi-standard percutaneous nephrolithotomy (control group). Group 2 (CT < 1,000) included 21 patients who underwent puncture-assisted single standard PCNL combined with ureteroscopic laser lithotripsy (experimental group), and 33 patients who underwent transurethral ureteroscopic laser lithotripsy (control group). The surgical variables including intraoperative blood loss, operative time, hospital stay, stone clearance rate, and postoperative complications were recorded. Statistical analysis was performed using chi-square test or Fisher's exact test for categorical data, and Results: The two groups were comparable in terms of age, sex, BMI, hypertension, coronary heart disease, diabetes, and preoperative white blood cell count ( Conclusion: For complex non-hydronephrotic renal stones, a CT value ≥ 1,000 should be treated with single standard PCNL using a puncture-assisted method; a CT value < 1,000 is better treated with a combination of puncture-assisted single standard PCNL and ureteroscopic laser lithotripsy, with higher safety and efficacy.
