Obstetric, perineal, and psychosocial outcomes after successful vaginismus treatment: a retrospective cohort study stratified by Lamont grade.

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
backgroundWhether obstetric, perineal, and psychosocial differences persist after successful vaginismus treatment, particularly by pre-treatment severity, remains unclear.
methodsIn this single-center retrospective cohort study, primigravid women who conceived spontaneously after successful vaginismus treatment and delivered between December 2023 and December 2025 (n = 117) were compared with controls selected at a 1:3 ratio for similar maternal age, body mass index, and gestational age at delivery (n = 351). Pre-treatment severity was graded by Lamont (1–4). Outcomes included cesarean delivery (overall and by Lamont grade), cesarean on maternal request, second-stage cesarean, neonatal outcomes, and Obstetric anal sphincter injuries (OASIS) (grades 3a-4). Prenatal psychosocial adjustment was assessed at 30 weeks (PSEQ total and PSEQ-FHL), and postpartum depressive symptom risk at 6 weeks (EPDS ≥ 13).
resultsBaseline characteristics were similar. Overall cesarean delivery was comparable (43.6% vs. 36.2%; OR 1.36, 95% CI 0.89–2.09), but Lamont grade 4 had a higher cesarean rate than controls (58.1% vs. 36.2%; OR 2.44, 95% CI 1.16–5.15). Cesarean on maternal request (17.9% vs. 5.4%; OR 3.82, 95% CI 1.97–7.40) and second-stage cesarean (5.1% vs. 0.6%; OR 9.43, 95% CI 1.88–47.40) were more frequent in the treated cohort. In vaginal deliveries (treated n = 66; controls n = 224), minor OASIS (3a-3b) was higher after treatment (9.1% vs. 2.2%; OR 4.38, 95% CI 1.29–14.85), and major OASIS (3c-4) occurred only in Lamont grade 4 (15.4% vs. 0.0%; p = 0.003). EPDS ≥ 13 did not differ overall (30.8% vs. 28.5%). PSEQ scores were higher in treated women, mainly in Lamont grades 3–4, indicating poorer late-pregnancy psychosocial adjustment.
conclusionsAfter successful vaginismus treatment, most maternal and neonatal outcomes were similar to controls; however, cesarean on maternal request and second-stage cesarean remained more frequent, minor OASIS was increased in vaginal deliveries, and major OASIS was concentrated in Lamont grade 4. Higher Lamont grades were also associated with poorer prenatal psychosocial adjustment.
