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
backgroundDupuytren's disease causes progressive flexion contractures and impaired hand function. While percutaneous needle aponeurotomy (PNA) provides rapid correction with low morbidity, the effect on grip strength remains unclear. Grip strength is a key surrogate of hand function and overall health, yet it has been inconsistently evaluated as an outcome in Dupuytren's disease.
methodsA prospective study was conducted at a tertiary referral center including 53 patients (80 digits) treated with PNA between February 2024 and March 2025. Standardized assessments included grip strength (Jamar dynamometer, American Society of Hand Therapists protocol), joint extension deficits, patient-reported outcomes (Southampton, Unité Rhumatologique des Affections de la Main [URAM]), and return-to-work data. Grip strength was reassessed at 2 months postprocedure to capture early functional recovery. Statistical analysis used paired
resultsMean grip strength improved from 24.9 to 28.7 kg (mean change + 3.8 kg,
conclusionsPercutaneous needle aponeurotomy (PNA) not only corrects digital contracture but also yields clinically significant improvements in grip strength, reinforcing its value as a functional outcome measure. These findings support PNA as a safe, effective first-line treatment for selected patients with Dupuytren's disease.
