Efficacy of shankh blowing on moderate sleep apnoea: a randomised control trial.
Article in ERJ open research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: The aim was to determine the effect of shankh (conch shell) blowing on sleep-related outcomes in individuals with moderate obstructive sleep apnoea (OSA). Methods: This was a prospective open-label randomised control trial with parallel groups including individuals with daytime sleepiness and recent moderate OSA diagnosis. Participants received either intervention of shankh blowing or a sham procedure (deep-breathing exercise) for 6 months. The primary outcome included daytime sleepiness (Epworth Sleepiness Scale; ESS) with two secondary outcomes of sleep quality (Pittsburgh Quality of Sleep Index; PSQI) and the apnoea-hypopnoea index (AHI). Linear mixed-effects models were used to assess outcomes. Results: Among 30 individuals with moderate OSA, 16 were randomised to the control group and 14 to the intervention group using unrestricted randomisation. Participants in the intervention group had a greater improvement in sleepiness with a 34% reduction in ESS score (change, -5.0 points, 95% CI -8.06- -1.93), and a significant change in the mean difference of the ESS score (-4.69 points, 95% CI -8.39- -1.007; p=0.0145) between groups at the end of the intervention. Sleep quality (PSQI score; change, -1.8 points, 95% CI -3.3- -0.26) and AHI (change, -4.4 events·h Conclusions: The observed improvements in daytime sleepiness, sleep quality and AHI suggest that respiratory muscle training through shankh blowing may emerge as a novel therapeutic option for managing OSA symptoms in the future.
