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 hypothesisSeventy percent of women with pelvic floor muscle (PFM) dysfunction are unable to contract these muscles correctly. Instruction to contract properly is essential for effective PFM training (PFMT). The study aimed to compare two groups of women with stress urinary incontinence (SUI): one group that received verbal instructions and body awareness techniques, and a second group that also incorporated vaginal palpation.
methodsRandomized control trial with two groups; 176 women with SUI were included (n = 88 in each group). The experimental group received vaginal palpation, body awareness techniques, and verbal instructions on PFM anatomy and function. The control group received similar body awareness techniques and verbal instructions. The primary outcome was the number of PFM fast voluntary contractions. Secondary outcomes included PFM performance (Oxford scale) and endurance, simultaneous external muscles groups (abdominal, gluteal, hip adductor) contractions, and self-efficacy and expectations for the results. Outcomes were measured after a 4-week intervention. Per-protocol (PP) and intention-to-treat (ITT) analysis were performed. P value ≤ 0.05 was considered statistically significant.
resultsBoth interventions groups increased the number of fast voluntary contractions [PP OR -0.1 (95% CI -0.8 to 0.5), p = 0.717]; (ITT p = 0.804). PFM voluntary contraction (p = 0.121) and muscle endurance (p = 0.757) were similar between groups. Reduction in simultaneous contractions of gluteus maximus was more pronounced in the experimental group compared to the control group (8.9% vs. 26.9% of patients, respectively; p = 0.003). Both groups showed similar ability to perform PFM contractions and similar self-perception of results, motivation, and confidence of PFM exercises.
conclusionsVaginal palpation provided limited additional benefit in improving voluntary PFM performance in women able to perform an initial voluntary contraction but was associated with improved contraction selectivity.
