1 · What the graph read from it

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.

2 · The registry

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

Pediatric patients are particularly susceptible to ionizing radiation risks. A fluoroscopy-free mini-percutaneous nephrolithotomy (mini-PCNL) was performed using computed tomography (CT)-ultrasound fusion guidance for recurrent cystine nephrolithiasis in a 12-year-old boy. Renal access and complete stone clearance were achieved. Integrating preoperative CT with real-time ultrasonography enabled precise targeting, overcoming limitations of ultrasound-only guidance. The procedure was completed safely, with minimal blood loss and 90-min operative time. CT-ultrasound fusion-guided mini-PCNL is a feasible radiation-sparing approach for pediatric patients with complex renal stones.
