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
Introduction: Unilateral mastectomy induces postural alterations; however, the resolution of this issue in clinical settings remains unknown. This study aimed to explore the effects of wearing external breast prosthesis on the posture of patients after unilateral mastectomy. Methods: A total of 240 patients who underwent unilateral mastectomy for breast cancer in our hospital's breast surgery department from September 2020 to March 2021 were selected, and they were registered and randomized in a 1:1 ratio to receive one of two treatments: (1) the intervention group wearing a external breast prosthesis (similar in weight to the breast) and (2) the control group wearing a cotton breast prosthesis (almost no weight). The generalized estimating equation method was used to analyze the impact of wearing external breast prosthesis on the patients' body posture 3 and 6 months after the intervention. Results: Statistically significant differences were observed between the two groups regarding forward head posture, shoulder asymmetry, scapular tilt, and neck tilt (P < 0.05). However, the two groups had no significant differences in scapular adduction/abduction, pelvic tilt, and trunk inclination (P > 0.05). Over time, all degrees of deviation in postural abnormalities exhibited an upward trend, with postural abnormalities becoming increasingly serious. Discussion: External breast prosthesis can improve postural abnormalities in patients with forward head posture, shoulder asymmetry, and scapular and neck tilts. However, there was no significant improvement in the short-term body posture of the patients concerning scapular adduction/abduction, pelvic tilt, or trunk inclination, indicating that further research is required to understand the effects of wearing external breast prosthesis on patients' body posture.
