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

Background: Most conventional cardiotocographs (CTG) work on the ultrasound principle and are heavily used by doctors to measure fetal heart rate (FHR) and uterine contractions (UCs). Despite their widespread usage, they have limitations with accessibility, portability and ease of use. Electrocardiogram (ECG) which relies on electrical signals gives a far superior signal during labor, yet it is ineffective to measure FHR unless an invasive scalp electrode is inserted. Noninvasive fECGs (ni-fECG) are still subject to constant research and validation. The ni-fECG device is a novel, ECG and electromyography (EMG)-based medical device that measures FHR, UC and maternal heart rate (MHR) continuously. It is portable, wearable and easy to use. This study aimed to assess the accuracy of the ni-fECG device with the conventional ultrasound-based CTG. Methods: A prospective observational study was conducted on 282 pregnant women. The inclusion criteria included women ≥ 28 weeks of gestational age with singleton pregnancy and cephalic presentation. The procedure used in both the devices to monitor FHR and UC was explained to the participants. Data analysis was done using Python Jupyter Notebook. Results: The accuracy for baseline heart rate, FHR and UC was found to be 97.37%, 91.3% and 70.27%, respectively. BMI and maternal age did not have a significant impact on the comparative accuracy. Conclusion: With further improvements in UC accuracy the ni-fECG device could be a viable alternative to CTGs.
