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
aimsThe aim of this study was to test the feasibility of mobilizing an acromial periosteal flap (APF) and to evaluate its potential to provide locally available, additional biological autologous augmentation for acute and chronic acromioclavicular joint (ACJ) injuries.
methodsTen cadaveric upper extremities (5 right, 5 left; 3 female, 7 male) with an average age of 82 ± 3.7 years were used. A direct surgical approach to the ACJ was performed, and the APF was mobilized from three sides of the acromion, leaving the side closest to the clavicle intact. The flap was folded over onto the clavicle and secured with a transosseous suture. Measurements of flap length, width, and clavicular overlap were recorded.
resultsMobilization of the APF was successfully achieved in all specimens. The flaps appeared clinically stable and tear-resistant, with an average length of 2.3 ± 0.5 cm, width of 1.75 ± 0.5 cm, and clavicular overlap of 1.29 ± 0.6 cm.
conclusionOur study demonstrated the anatomical feasibility of preparing an acromial periosteal flap (APF). This anatomical proof of concept may provide the basis for potential future clinical applications as an additional option for biological augmentation in ACJ reconstruction. However, further biomechanical investigations and clinical studies are necessary to evaluate whether this technique can translate into improved stability and functional outcomes.
