Characteristics and evolution of pelvic floor structures in female patients aged over 40 years with constipation-a retrospective cohort study.
Article in PeerJ, 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
Background: Pelvic floor dysfunction (PFD) is a common cause of chronic constipation which can reciprocally exacerbate pelvic floor burden. However, the characteristics and evolution of pelvic floor structures in patients with constipation remain unclear. This study investigates the characteristics and evolution of pelvic floor structures in constipated women aged over 40 years. Methods: Clinical data were collected from female patients undergoing pelvic floor ultrasound at the Third Affiliated Hospital of Sun Yat-sen University from December 2020 to August 2023. Propensity score matching (PSM) minimized confounders between the constipation ( Results: Significant intergroup differences emerged in uterine prolapse ( Conclusion: This study demonstrates that rectocele and uterine descent at maximal VM exhibit positive associations with constipation. Over time, further descent of the bladder, uterus, and rectum occurs in female patients with constipation, along with an increase in perineal mobility and levator ani hiatus area.
