Morphological Changes in Rectus Abdominis Muscle Associated With Pregnancy and Abdominoplasty.
Article in Aesthetic surgery journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPregnancy can alter the rectus abdominis, but abdominoplasty can potentially correct these changes.
objectivesThe aim of this study was to examine these muscle changes during pregnancy and to evaluate how effectively abdominoplasty with double folds of the rectus abdominis tightens the muscle.
methodsClinical data were obtained from nulliparous and pregnant patients who had undergone abdominoplasty with double folds of the rectus abdominis. Measurements were made of linea alba width, rectus abdominis width, thickness, and cross-sectional area, and abdominal circumference. Postoperative complications were also recorded. Patient satisfaction with the morphology of the rectus abdominis, both pre- and postsurgery, was assessed on a 5-point Likert scale.
resultsThe study included 400 women: 171 nulliparous, 106 with 1 pregnancy (Group 1), and 123 with 2 or more pregnancies (Group 2). Complete postoperative data were available for 32 patients (Group 3). Significant widening of the linea alba was found in Groups 1 and 2. The rectus abdominis width increased significantly in Group 1 but not in Group 2. Its thickness remained unchanged in Group 1 but decreased in Group 2, mirroring the pattern of its cross-sectional area. In Group 3, both the linea alba and rectus abdominis width decreased, while thickness and cross-sectional area increased. Satisfaction with muscle morphology improved significantly postsurgery, with no serious complications reported.
conclusionsPregnancy can cause the rectus abdominis muscle to separate, widening the linea alba and flattening the muscle. Abdominoplasty, which reinforces the muscle with double folds, effectively resolves this, resulting in high patient satisfaction and few complications. LEVEL OF EVIDENCE: 3:
