Improving Nausea Through Breathing Interventions: A Trial of Written Instructions for Diaphragmatic Breathing Versus a Biofeedback Device.
Trial report in Canadian journal of gastroenterology & hepatology, 2026. 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
backgroundNausea is a distressing symptom affecting ∼7% of the population. Pharmacologic options are limited and often ineffective for chronic nausea. Nonpharmacologic strategies, such as breathing exercises, have shown promise in reducing stress and GI symptoms, but their role in chronic nausea has not been studied. This study addresses this knowledge gap by comparing written diaphragmatic breathing (DB) instructions with a biofeedback device (CalmiGo) for their effect on nausea severity.
methodsIn a prospective study, we investigated the effects of breathing exercises using either written instructions for DB or a biofeedback respiratory practice device (CalmiGo) on self-reported severity of nausea. Participants were randomized to either intervention and asked to practice the exercises three times daily for 3 min each time for 6 Weeks. Nausea was evaluated at baseline and every week for 7 Weeks via online self-reported surveys.
resultsA total of 85 adults with nausea (n = 44, 51.7% severe nausea) were randomized to either DB (n = 36) or CalmiGo (n = 49). There was no difference between the two groups at baseline in demographic features, anxiety, depression, or nausea severity. Nausea improved at all-time points in both groups with a medium to large effect size. However, after applying false discovery rate correction, the improvement remained significant for DB only at weeks one to three and borderline significant at weeks four to five and Week 7. There was no difference in response rates between the two groups. Age, body mass index, baseline anxiety, and whether one was diabetic were predictive of improvement in nausea after 4 Weeks.
conclusionIn a pilot study, we observed that brief breathing exercises improve nausea. Breathing exercises may be useful as a nonpharmacologic option in the management of nausea, although larger trials are needed to confirm these findings.
