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
In order to reduce the energy loss during data transmission and storage in the Internet of Things system and improve the transmission efficiency of fetal heart rate data to allow real-time monitoring of the fetus, we used a convolutional codec network (CC-Net) to compress the data. The network has two modules: the encoding and decoding modules. The original data are compressed in the encoding module and reconstructed in the decoding module. The internal parameters are continuously updated using the mean square error of the original and the reconstructed signals to minimize the error to obtain effectively compressed data in the encoding module. In this study, the compression ratio of fetal heart rate signals using this method reached 12.07%, and the error between the reconstructed and original signals was 0.03. The proposed CC-Net can achieve a very low compression ratio for fetal heart rate compression while ensuring a high similarity between the reconstructed and the original signals to retain important information in fetal heart rate signals.
