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
Background: Urinary stones are a common disease in urology, and stones in ureteral strictures can easily lead to obstruction and subsequent infection. If the upper ureteral impacted stones with infection are not treated promptly, further renal impairment and urinary sepsis can occur. Mini-percutaneous nephrolithotomy (PCNL) and flexible ureteroscopic lithotripsy (fURSL) are common methods for the treatment of upper ureteral impacted stones with infection, but their superiority remains debated. To this end, we designed this study to compare the effects of mini-PCNL versus fURSL in patients with upper ureteral impacted stones with infection. Methods: The data of 182 patients with upper ureteral impacted stones and infection admitted to The First Affiliated Hospital of Chengdu Medical College from January 2021 to December 2024 were retrospectively collected. The patients were divided into an antegrade group (n=88) and a retrograde group (n=94) according to the method they received. The antegrade group was treated with minimally invasive PCNL, and the retrograde group was treated with fURSL. The main outcome measure included inflammatory markers [white blood cell count (WBC), C-reactive protein, interleukin 6, and procalcitonin], and renal function (serum creatinine and urea nitrogen). The other indicators included surgery-related outcomes (operation time and stone-free status) and postoperative complications. Results: Compared with the retrograde group, the one-time stone clearance rate in the antegrade group was significantly higher (96.59% Conclusions: PCNL can improve stone clearance rate, but the operation time is long and relatively invasive.
