Effect of OM Chanting of 528Hz Frequency on Heart Rate Variability, Psychological Wellbeing, and Quality of Sleep in Patients of Hypertension: A Randomised Controlled Trial.

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
Background: Hypertension (HTN) is associated with lower heart rate variability (HRV) and multiple psychological and sleep disturbances. OM chanting, a scriptural form of meditation, has been shown to improve multiple cardiac, psychological, and autonomic factors in different cohorts. Purpose: To investigate the effects of listening to OM chanting composed at 528Hz on heart rate, blood pressure, HRV, psychological general wellbeing, and quality of sleep in patients with HTN. Methods: Sixty patients with diagnosed Stage 1 HTN were randomised into control and intervention groups. Patients in the experimental group listened to an audio recording of OM chanting daily for one month. Patients in the control group received standard care. Outcome measures were assessed immediately after the first session and at the end of one month. Results: After one month of intervention, a significant ( Conclusion: Listening to 528 Hz frequency OM chanting for one month reduces pulse and blood pressure, and enhances parasympathetic dominance on HRV analysis. It also improves psychological wellbeing, reduces perceived stress, and improves the quality of sleep. OM can be considered an important non-pharmacologic therapy in HTN. It is convenient, socially, and culturally acceptable, harmless, and in sync with deeply rooted religious/spiritual practices of the community.
