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
backgroundThis study aimed to determine the morphological differences of three-part proximal humerus fractures, the group in which plate screw fixation is most frequently used, and to evaluate the functional and radiological results of the methods applied for different subgroups.
methodsTwenty-nine patients (6 males and 23 females) with three-part proximal humerus fractures were in the study, with an average age of 64. The patients were in three groups according to their fracture types. Group 1 included eight patients with valgus impaction fracture. Group 2 included eleven patients with easily achieved stability after reduction. Group 3 consisted of ten patients with procurvatum varus angulation, a significant displacement between fragments, and in whom medial cortical continuity was not maintained without fixation. All patients underwent surgery with a minimally invasive deltoid split approach method and locked ana-tomic plate screw osteosynthesis. In group 1 patients, the space in the area where valgization is present in the head was filled with cortico-cancellous allografts. No grafting or metaphyseal compression took place in Group 2 patients. In group 3 patients, the metaphyseal compression technique was applied to the bone defect area. Cephalodiaphyseal angles (CDA) were measured at the postoperative and final follow-up. The constant Murley score made the functional evaluation.
resultsThe patients were followed for an average of 27.6 months, and the union was present in all patients for an average of 3.6 months. Early screw migration was present in three patients, and late screw migration was in one patient. There were twenty-four excellent and 5 good results. CDA decreased from 139.42° to 136.13°. A statistically significant difference was present between the values of Groups 2 and 3 in the final control CDA of the groups.
conclusionIn this study, the functional scores of grafting stable valgus-impacted fractures and metaphyseal compression of unstable fractures with insufficient medial support were as good as stable 3-part fractures. Considering neer type 3 fractures should be evaluated with their subgroups, and fixation and stability-enhancing solutions specific to the groups are essential.
