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
backgroundWe aimed to determine the minimum effective period of mandibulomaxillary fixation after the inadequate internal fixation of Le Fort I or Le Fort II fracture.
objectiveThe aim of this study was to investigate the stability of the skeleton after the treatment of Le Fort I or Le Fort II fractures by measuring bite forces and to determine the minimum time required for effective mandibulomaxillary fixation following treatment with internal fixation and mandibulomaxillary fixation.
methodA prospective study was performed to examine the treatment of Le Fort I or Le Fort II fracture in the Department of Maxillofacial Surgery at the National Hospital of Odonto-Stomatology in Ho Chi Minh City, Vietnam. A total of 31 patients were included, with up to 1 month of follow-up after discharge from the hospital. Midface bone stability and the mandibulomaxillary fixation time were evaluated using bite force criteria after 1, 2, and 4 weeks.
resultsMidface bone stability values 1, 2, and 4 weeks after treatment were 87.1%, 100%, and 100%, respectively. After 1 week, 87.1% of patients achieved intermaxillary fixation, and 96.3% of these patients were treated with at least three rigid plates. The remaining 12.9% of patients achieved fixation after 2 weeks, and all of these patients were fixed only at zygomaticomaxillary sutures (p < 0.05). Bite forces increased significantly at 2 weeks compared with 1 week and at 4 weeks compared with 2 weeks (p < 0.05).
conclusionWhen treated using only rigid fixation, through the placement of plates and screws at zygomaticomaxillary buttresses, patients with Le Fort I and Le Fort II fractures can achieve mandibulomaxillary fixation after 2 weeks. For Le Fort I fractures, rigid fixation using plates and screws at zygomaticomaxillary buttresses and canine buttress at three positions can achieve mandibulomaxillary fixation after only 1 week (p = 0.0001).
