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
backgroundStandard flexible ureteroscopy lithotripsy (FURL) for upper urinary tract infectious stones carries risks of high intrarenal pressure (IPP) and postoperative infection. We evaluated whether an intelligent pressure-guided system improves outcomes.
methodsThis retrospective study included 269 patients with upper urinary tract infectious stones that were received by the First Hospital of Hebei Medical University from May 2022 to December 2025. Patients were divided into the Standard Group (n = 142, standard FURL) and the Intelligent Group (n = 127, intelligent pressure-guided FURL). Primary outcomes were stone-free rate (SFR) at postoperative day 1, 1, and 3 months, during key procedural stages, and complications. Secondary outcomes included operative time, hospital stay, renal function, and inflammatory markers.
resultsThe Intelligent Group achieved significantly higher SFRs at day 1 (87.40% vs. 73.24%,
conclusionsIntelligent pressure-guided FURL improves stone clearance, shortens convalescence, and reduces infectious complications compared to standard FURL for upper urinary tract infectious stones.
