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
backgroundIt is common for physicians to opt for surgical correction of hallux valgus deformities using implants, but post-operative complications are frequently reported. A novel h-shaped plate developed by the authors offers both endosteal and lateral fixation, helping to resist displacement in multiple directions. This study aims to assess the mechanical properties and stability of the h-shaped plate in comparison to various commercially available endosteal plating systems in a simulated hallux valgus correction model using finite element analysis.
methodsFinite element models of four different endosteal plates were developed and used to simulate a hallux valgus correction. The distal end of the metatarsal in each model was loaded at 87.5 N, which is the maximum load experienced during cyclic testing. The load was applied in various directions to simulate different metatarsal movements, including plantar flexion, dorsiflexion, abduction, and adduction of the first metatarsal bone. The mechanical properties and stability of each model was recorded for comparison.
resultsWhen placed under dorsal-to-plantar loading, the model with a h-shaped plate was the most stable of all models, with a displacement of 0.278 mm, plate stress of 429.51 MPa, and screw stress of 294.97 MPa. Under medial-to-lateral loading, the model with a h-shaped plate demonstrated the lowest displacement of 0.152 mm, and plate and screw stresses of 254.27 MPa and 195.40 MPa, respectively.
conclusionFor stabilizing distal chevron osteotomies, the h-shaped bone plate showed greater resistance to displacement in the dorsal-to-plantar and medial-to-lateral directions than the commercially available implants evaluated in this study. The h-shaped plate also presented a lower risk of screw pull-out, which helps to maintain bone alignment postoperatively.
