The comparison of spread of methylene blue after the Pericapsular Nerve Group block and a double injection selectively targeting the articular branches to the anterior hip capsule in human cadavers.
Article in Pain practice : the official journal of World Institute of Pain, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesIn this study, the spread of methylene blue was compared between an ultrasound-guided Pericapsular Nerve Group (PENG) block and a double injection technique, where the approach towards the inferomedial acetabulum was added to the latter.
methodsThe two techniques were performed in 11 fresh frozen cadavers. The spread was measured after anatomical dissection in which the supplying femoral and obturator nerves were identified. RESULTS AND
conclusionOur study demonstrates adequate staining of the iliac bone with comparable distal and medial spread in both techniques, indicating that the PENG block with a single injection is adequate in blocking the hip capsule with 10 mL local anesthetics. Staining of the femoral nerve occurred in 2/6 specimens after the PENG block, and staining of the obturator nerve in 1 specimen in each group.
