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
purposePercutaneous nephrolithotomy (PCNL) is an effective treatment for large kidney stones, but wider access paths increase the risk of bleeding. While modern miniaturized PCNL techniques reduce invasiveness, they can compromise stone fragment clearance. This study aims to evaluate the efficacy and safety of a novel PCNL technique utilizing pediatric trocar laparoscopy to enhance visualization and potentially minimize blood loss.
methodsA single-centered prospective study was conducted at Sultan Agung Islamic Hospital, Semarang, Indonesia, between July and September 2024. Patients with large kidney stones underwent a novel technique replacing PCNL after obtaining informed consent. The primary endpoints measured were stone-free rate and major complications after the procedure.
resultsForty-four participants were enrolled in this study, with 41 completing it. The 24-hour stone-free rate was 87.8%, improving to 100% at 30 days. The mean operative time was 42 ± 13.6 min, with an average hospital stay of 2.39 ± 0.81 days. No major complications were reported. The mean hemoglobin drop was minimal, and transient postoperative leukocytosis without clinical infection was observed.
conclusionThis study suggests that a novel technique for treating large kidney stones using a 3.5 mm laparoscopic trocar in PCNL is considered an effective and safe procedure as an alternative to the standard PCNL procedure.
