Effectiveness of Biofeedback with Dilator Therapy for Sexual Function in Women with Primary Vaginismus: Randomized Controlled Trial Study.
Trial report in International urogynecology 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
introduction and hypothesisVaginismus is characterized by the involuntary spasm of the pelvic floor muscles (PFMs) around the outer third of the vagina, leading to difficulties in vaginal penetration. Physical therapists often use biofeedback to help individuals to gain better control over their muscles. This study was aimed at assessing the impact of biofeedback with dilator therapy on sexual function in women with primary vaginismus.
methodsIn this randomized controlled trial study, 32 women with primary vaginismus, aged 18 to 45, were randomly assigned to either the experimental group (n = 16) or the control group (n = 16). The experimental group received both dilator therapy and biofeedback training, whereas the control group only received dilator therapy. Both groups followed a 6-week, twice-a-week session program. The Female Sexual Function Index (FSFI) questionnaire, which includes six dimensions (desire, arousal, lubrication, orgasm, satisfaction, and pain), was administered before and after the 6-week treatment, as well as 1 month after completion.
resultsThe analysis of variance test showed that the interaction effect of the group and time on the overall score of sexual function (p < 0.001) and the aspects of desire (p < 0.001), arousal (p < 0.001), orgasm (p = 0.028), satisfaction (p < 0.001), and pain (p = 0.003) were significant; however, the interaction between group and time (p = 0.182) was not observed for lubrication.
conclusionBiofeedback therapy combined with dilator therapy and dilator therapy alone are both effective in improving sexual function in women with primary vaginismus. However, women undergoing biofeedback combined with dilator therapy seem to benefit more than those receiving dilators alone.
