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
backgroundPlate fixation is a widely used surgical procedure for proximal humeral fracture; however, relatively high complication rates have been reported. To prevent the occurrence of proximal screw cut out, pegs with blunt tips have been introduced to replace traditional screws for fixation of the humeral head. However, few reports are available on the effect of using smooth pegs on surgical outcomes. In this study, we aimed to compare the postoperative outcomes of osteosynthesis using anatomical plates using all proximal screws and using all proximal pegs.
methodsWe retrospectively identified 48 patients who underwent osteosynthesis using an anatomical locking plate for proximal humeral fractures. We divided the patients into a screw group (25 patients) and a peg group (23 patients) according to the devices used to fix the humeral head. We compared operative outcomes, postoperative shoulder functional scores, and postoperative complication rates between the two groups.
resultsIn terms of operative outcomes, the operation time was significantly shorter in the peg group than that in the screw group (94 [83–105] min vs. 114 [98–124] min, p < 0.001, r = 0.52). No significant differences in adjusted Constant score and American Shoulder and Elbow Surgeon score were observed at 1 year postoperatively between the two groups. However, the incidence of greater tuberosity reduction loss was significantly higher in the peg group than that in the screw group (17.4% vs. 0%, p = 0.046, φ = 0.32).
conclusionsOur study showed that the use of proximal pegs did not significantly affect postoperative shoulder functional outcomes, although it may reduce operative time. In three-part fractures involving the greater tuberosity, the use of proximal screws or plates with sufficient coverage of the greater tuberosity may be desirable to prevent reduction loss of the greater tuberosity.
