Diagnostic accuracy of wearable ECG and assessment of ventricular repolarization and its cardiovascular risks post cold stress.

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
Cold stress can affect ventricular repolarization (VR), which may serve as a potential trigger for malignant arrhythmias. Compared to conventional electrocardiogram (ECG) devices, wearable technology is more suitable for out-of-hospital monitoring due to their portability. However, outdoor cold environments can limit their application. We aimed to develop a wearable ECG capable of functioning in a cold environment. Moreover, to explore the impact of cold stress on VR parameters in a real-world cold environment and identify associated cardiovascular risks. A self-developed handheld 12-lead wearable ECG was utilized, featuring a fabric electrode and a novel "sandwich" design to enhance its applicability in cold environments. A total of 152 healthy adults were enrolled and both conventional and wearable ECG were performed on them. The results from testing under an outdoor cold environment indicated that the parameters of the ECG measured by the wearable device were in good agreement with those measured by the conventional machine. Those with higher baseline heart rate (HR) were at increased risk of prolonged QT
