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: To assess the clinical feasibility and safety of exercise magnetocardiographic stress test based on optically pumped magnetometers (OPMs). Methods: Subjects without previous cardiovascular disease were enrolled in this study. All subjects underwent exercise electrocardiographic stress test (EST) and both rest and stress OPM-based magnetocardiography (MCG). Results: A total of 26 healthy subjects finally enrolled in this study. None of the subjects reported chest pain, dyspnea or any other discomfort during the test. The mean interval between the completion of EST and the initiation of OPM-based MCG signal acquisition was 60.3 ± 8.4 s. One subject observed obvious deflection of magnetic field (Unstable-MCG group) during stress OPM-based MCG, whereas 25 subjects did not (Stable-MCG group). In Stable-MCG group, the rest and stress magnetocardiographic parameters were phenotypically similar ( Conclusion: We demonstrated an innovative diagnostic technology with broad potential application value for diagnosing myocardial ischemia and assessed its clinical feasibility and safety. This is a critical step toward making the examination widely used in clinical practice.
