Magnetomyographic assessment of pelvic floor muscles compared to ultrasound during pregnancy.
Article in Physiological reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Maternal birth injury contributes to future pelvic floor disorders, yet we possess an incomplete understanding of the levator ani muscles during pregnancy. We applied a noninvasive magnetomyography technique to characterize levator ani muscle activity in pregnancy with ultrasound and clinical exam. Magnetomyographic measures of levator ani muscle activity were collected using a noninvasive biomagnetic sensor from 53 pregnant women during rest and voluntary muscle contractions of varying intensity. Power spectral density was calculated using Welch's method to obtain the mean power of each Kegel exercise. Levator hiatus circumference was measured using ultrasound, and contraction strength was measured via the Brink scale. Magnetomyography data revealed a mean root mean square (RMS) rest of 39.7 ± 8.6 femtoTesla (fT) and Kegel of 52.9 ± 17.1 fT. Mean power spectral density (PSD) in log
