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

Ultrasonography is widely used for fetal monitoring but it requires sonographers and is limited to snapshot evaluations at discrete intervals. Here we report a wearable ultrasound patch (UPatch) for continuous and autonomous fetal monitoring. The UPatch can acquire anatomical structures and blood flow velocities, demonstrating good agreement with a handheld clinical ultrasound device on 62 pregnancies. Real-time image segmentation allows autonomous tracking of target vessels to acquire continuous blood flow spectra during fetal and maternal movements without a sonographer. Continuous monitoring data from 52 pregnant women aligned with stratified perinatal conditions, including healthy, small for gestational age, large for gestational age, gestational diabetes, preeclampsia and gestational hypertension. With further technology development, integration with a miniaturized circuit could enable fully wireless operation and greater user mobility. The UPatch could provide continuous assessment of fetal compromise in high-risk pregnancies, expanding prenatal-care capabilities.
