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
purposeSeveral surgical techniques have been used for shoulder fracture treatment. In 1989, Kapandji described the 'Palm Tree technique' for the first time, consisting of inserting three K-bent wires through a bone hole created under deltoid muscle insertion. The purpose of this study was to evaluate clinical and radiographic results of proximal humerus fractures treated by a modified "palm tree technique."
methodsFrom August 2021 to March 2025, 43 patients with proximal humerus fractures underwent surgical treatment using the modified Palm Tree technique. The mean age was 61.8 years (range, 17-85 years), with a mean follow-up of 17.4 months (range, 6-24 months). According to the Neer classification, two-part, three-part, and four-part fractures were treated by this technique, all performed by the same surgeon. Clinical outcomes were assessed using the Constant Score, UCLA Shoulder Rating Scale, and DASH scores.
resultsA total of 43 patients were included in the final analysis. The mean Constant Score was 79.3 ± 25.4, the mean UCLA score was 27.3 ± 10.0, and the mean DASH score was 18.5 ± 25.9. Six cases (14.0%) of K-wire migrations were encountered whereas two cases (4.7%) of avascular necrosis of the head required shoulder arthroplasty. One patient developed non-union (2.3%) and another secondary loss of reduction. No neurovascular injury or fracture at the entry site has been reported.
conclusionsThe modified Palm Tree technique appears to represent a feasible, joint-preserving, minimally invasive treatment option for selected proximal humeral fractures, providing favorable functional and radiographic outcomes. Careful patient selection remains essential, particularly in elderly patients with poor bone quality.
