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: Fixed orthodontic appliances, such as stainless steel and titanium brackets, might become exposed to magnetic resonance imaging (MRI) during treatment. However, the effects of MRI on microleakage and thermal changes in these brackets have not been thoroughly investigated. This study addresses these gaps to ensure safety and efficacy in patients undergoing orthodontic treatment while exposed to MRI. Purpose: This study investigates and compares the effects of 1.5 tesla (T) MRI exposure on microleakage and temperature changes in stainless steel and titanium orthodontic brackets, evaluating their safety and bond integrity during orthodontic treatment. Materials and Method: In this Results: Microleakage at the enamel-adhesive interface was slightly higher than at the bracket-adhesive interface in all groups, but the differences were not statistically significant ( Conclusion: Exposure to a 1.5 T MRI magnetic field does not significantly affect microleakage or temperature changes in stainless steel or titanium brackets. These findings suggest that fixed orthodontic appliances do not need to be removed prior to MRI examinations, provided artifacts or image interference are not a concern.
