An Exploratory Randomised Trial to Assess the Effect of Nadi Shodhan Pranayama as an Adjunct Versus Standard Non-pharmacological Management in Hypertensives.

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: Nadi shodhan pranayama, which is also known as Anulom-vilom pranayama or alternate nostril breathing, has been demonstrated to elicit a decrease in systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate, owing to its stress-reducing effects. One of the most promising quantitative markers of autonomic activity is heart rate variability (HRV). Purpose: This study was done to study the immediate and long-term effects of 10 minutes of nadi shodhan pranayama, preceded by two minutes of yogic deep abdominal breathing, on blood pressure and other autonomic parameters. Methods: Baseline parameters of BP, HRV, Pittsburgh Sleep Quality Index (PSQI) and Hamilton Anxiety Rating Scale (HAM-A) were measured at first visit. Patients were randomised into test and control groups, and the test group was given intervention. BP and HRV were measured once again immediately after intervention for test subjects. After six weeks, BP, HRV, PSQI and HAM-A were repeated. Results: Immediately after the intervention, the test group showed a significant reduction in SBP, DBP and mean heart rate (MHR) with an increase in R-R interval, standard deviation of the NN interval (SDNN), the square root of the mean squared differences of successive NN intervals and high frequency. At follow-up, the test group had a lower SBP and low frequency/high frequency ratio and a higher SDNN and total power, compared to the control group. Conclusion: The practice of nadi shodhan pranayama, preceded by two minutes of yogic deep abdominal breathing, reduced the systolic and diastolic BP and improved HRV-related autonomic parameters, in patients of hypertension on pharmacological therapy, immediately after 10 minutes of practice and after 10 minutes of daily practice for six weeks.
