Ultrasonic evaluation of the master knot of henry: anatomical relationships and predictive modeling.
Article in Journal of medical ultrasonics (2001), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo explore the value of ultrasound in evaluating the anatomical structures around the master knot of Henry (MKH).
methodsUltrasound examinations were performed on 200 feet of 100 adult volunteers. The length of each foot was measured, and the distances from the medial border of the MKH to the medial malleolus (MM), the navicular tuberosity (NT), the interphalangeal joint of the hallux (IP), and the medial plantar artery (MPA) were measured. The layered tissues formed by the slipping of the tendon of the flexor hallucis longus (FHL), the quadratus plantae muscle (QP), and the tendon of the flexor digitorum longus (FDL) were determined. The ratios of each length variable to the foot length were calculated, and the relationship between each tendon-related parameter and the foot length was estimated based on regression analysis. The ability of ultrasound to display the relationship with plantar blood vessels, layered tissues, and other aspects was evaluated.
resultsThe average foot length was 23.27 ± 1.43 cm. Distances from MKH to MM, NT, IP, and MPA were 7.51 ± 0.75 cm, 1.92 ± 0.23 cm, 13.03 ± 0.69 cm, and 0.18 ± 0.05 cm, respectively. Layered structures: 97% two-layer, 3% three-layer. Foot length strongly correlated with MKH-MM, MKH-NT, and MKH-IP. A regression equation was derived to predict tendon-related parameters, aiding MKH-anatomical landmark relationships.
conclusionUltrasound examination holds significant value in evaluating the anatomical structures of the plantar region.
