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
Background: Fracture fixation, in the present times, is classically done using mini plates. The position and number of plates to fixate a mandibular angle fracture have been and are still extensively researched and reported in the literature. A more recent addition is 3D mini plates. Aim: To compare and evaluate the biomechanical behavior of one 2.0 mm titanium 3D miniplate fixation plate (4- hole) and one 2.0 mm titanium 4-hole miniplate in internal fixation of mandibular angle fractures. Objective: To measure load at break, maximum load, and displacement at maximal load for internal fixation done with 3D mini plates and conventional mini plates respectively. Methods: Five dry cadaveric mandibles were sectioned into 10 hemi-mandibles. Each cadaveric mandible was sectioned at the angle of mandible to simulate unfavorable mandibular angle fracture. The obtained hemimandible were divided into experimental groups (GROUP 1 and GROUP 2) with 5 samples in each group, plated with a linear miniplate and 3D miniplate respectively. Maximal load, Load at break, and displacement at maximum load were the only obtained parameters for comparison. Results: Conventional miniplate showed greater mean maximum load values of 174.93 N±54.45 compared to 3D mini plates which recorded a mean maximum load value of 106.96 N ± 23.86. Load at break and displacement at maximum load were found to be both insignificant. Conclusion: The results in this study showed statistically no significant difference with any of the above parameters except maximal load, between the two groups evaluated. Conventional linear miniplate according to Champy's lines of osteosynthesis can be used successfully for providing satisfactory osteosynthesis with the definitive advantage of cost-effectiveness.
