Low-Frequency Magnetic Stimulation of Shenmen Acupoint Reduces Blood Oxygen Levels in the Prefrontal Cortex of Healthy Subjects: A Near-Infrared Brain Functional Imaging Study.
Article in Chinese journal of integrative medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo explore the effect of low-frequency magnetic stimulation at Shenmen (HT 7) acupoint on blood oxygen levels in the prefrontal cortex of healthy subjects.
methodsFunctional near-infrared spectroscopy (fNIRS) technology was used to collect real-time data of oxygenated hemoglobin (oxy-Hb) in the prefrontal cortex of 16 healthy subjects at resting state and low-frequency magnetic stimulation of Shenmen. The mean and integral values of blood oxygen concentration were analyzed.
resultsCompared with the resting state, the mean and integral values of blood oxygen concentration were decreased during the task period, recovery period, and the whole process in the magnetic stimulation of Shenmen acupoint (P<0.05). In particular, the difference was statistically significant in the recovery period (P<0.01).
conclusionsThe prefrontal cortex was widely activated and produced an immediate effect by reducing the local blood oxygen concentration at low-frequency magnetic stimulation of Shenmen acupoint, which verifies the sedative effect of Shenmen acupoint.
