Influence of sheath size on suction mini-PCNL outcomes: An observational study from the EAU endourology section and the global suction in mini-PCNL collaborative study group.
Article in BJUI compass, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Objective: We aim to evaluate the association between sheath size and outcomes in suction mini-percutaneous nephrolithotomy (SM-PCNL). Materials and Methods: A prospective, multicentre study enrolled 1534 patients undergoing SM-PCNL from March to November 2024 across 30 centres. Patients were stratified into three groups: Group 1 (14-15 Fr, Results: Group 3 achieved the highest zero residual fragment rate (92.6%) compared to Groups 2 (80.7%) and 1 (79.5%) ( Conclusions: Sheath selection in SM-PCNL requires balancing efficacy against safety. Larger sheaths (20-22 Fr) optimize stone clearance but increase complications. Smaller sheaths (14-15 Fr) offer superior safety for simple cases. Intermediate sizes (16-18 Fr) may represent an optimal compromise for moderately complex stones.
