Immediate effect of abdominal muscle contraction on pelvic floor morphology in postpartum women.
Article in Frontiers in medicine, 2026. 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
Objective: This study aimed to explore the immediate effect of abdominal muscle contraction on the pelvic floor morphology in postpartum women. Methods: This observational cross-sectional repeated-measures study recruited 90 participants who visited the Fujian Maternity and Child Health Hospital from May 2024 to March 2026. All participants underwent pelvic floor assessments using four-dimensional (4D) ultrasound in seven different positions. Results: The results showed a general decreasing trend in the hiatal area and retrovesical angle and an increasing trend in the urethral tilt angle during pelvic floor muscle contraction. The bladder neck position, cervical position, and rectal ampulla position descended during drawing-in ( Conclusion: Drawing-in, head-lift, and flexion of the hips and knees were associated with immediate pelvic organ descent and hiatal area enlargement in this study, with the head-lift2 maneuver showing a relatively higher mechanical loading degree. The simultaneous contraction of the pelvic floor muscles during these maneuvers correlated with an immediate reduction in pelvic organ descent.
