1 · What the graph read from it

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.

2 · The registry

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 hypothesisThe purpose of the present study was to assess whether attempts at a maximal voluntary pelvic floor muscle (PFM) contraction can reduce vaginal resting pressure (VRP) and surface EMG activity in women with and without provoked vestibulodynia (PVD).

methodAn assessor blinded comparison study included 35 women with and 35 women without PVD. VRP and PFM strength were measured with a high precision pressure transducer connected to a vaginal balloon (Camtech AS, Sandvika Norway). PFM activity was measured before and after three MVCs with surface EMG (NeuroTrac ETS™; Verity Medical, Romsey, UK). Paired sample t test was used to analyze differences within groups and independent sample t test to analyze differences between groups. p value was set at <0.05.

resultsMean age of the participants was 24.3 years (SD 4.7) and mean BMI was 22.0 kg/m DISCUSSION: Young, nulliparous women with PVD had significantly lower vaginal resting pressure and sEMG activity after three maximum contractions of the PFM. The results indicate that attempts at voluntary maximal contractions may be investigated as a method of reducing PFM hypertonicity.
