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
This study compares the clinical efficacy of nephrostomy combined with flexible ureteroscopy versus conventional flexible ureteroscopy for complex upper ureteral stones. The clinical data of 68 patients with unilateral complex upper ureteral stones admitted to the Hospital Affiliated to Shaoxing College of Arts and Sciences from April 2021 to September 2023 were retrospectively analyzed, and they were divided into 2 groups according to whether or not they had undergone nephrostomy before lithotripsy, with 34 in each group; the experimental group was treated with nephrostomy combined with flexible ureteroscopy lithotripsy (FURL), and the control group was treated with FURL. The stone removal rate, operation time, intraoperative bleeding and complications of the 2 groups were compared. All patients successfully completed the treatment. The stone clearance rate was 94.1% in the experimental group and 76.5% in the control group; the operation time was (48.97 ± 14.25) min and (63.35 ± 17.76) min, respectively; intraoperative bleeding was (32.8 ± 6.1) ml and (53.4 ± 5.9) ml, respectively; serum creatinine at 3 days after operation was (89.7 ± 9.3) μmol/L and (96.1 ± 9.9) μmol/L; postoperative hospitalization days were (3.65 ± 0.98) day and (4.41 ± 1.28) day, respectively. Nephrostomy combined with flexible lithotripsy and conventional flexible lithotripsy are both safe and effective in the treatment of complex upper ureteral stones, but nephrostomy combined with flexible lithotripsy has a higher stone clearance rate, less intraoperative bleeding, and shorter operative time, which is worthy of clinical promotion.
