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
Magnesium (Mg) alloy screws represent promising biodegradable orthopedic implants owing to their biocompatibility, mechanical strength, and gradual resorption, thereby obviating the need for secondary removal surgery. However, their electrical conductivity raises safety concerns during magnetic resonance imaging (MRI) used for the assessment of healing progress and potential complications, where exposure to radiofrequency (RF) energy may induce tissue heating. As Mg implants degrade, evolving geometry and material phase may alter electromagnetic behavior, deposition of RF energy and potential heating. This study systematically examined the effects of key degradation mechanisms-volume reduction, surface roughening, formation of a magnesium hydroxide layer, and implant fractures-on MRI-induced heating. High-resolution electromagnetic field simulations at 3.0 T (ASTM F2182 phantom and realistic human voxel model) were complemented by thermal modeling and experimental MRI heating measurements using real-world screws. Volume loss and edge smoothing reduced maximum 1g-specific absorption rate (SAR
