L-Menthol Olfactory Stimulation Reduced Dyspnea Sensation during the 6 min Walk Test in Patients with Chronic Breathlessness Syndrome: A Pilot Study.
Article in Journal of clinical medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
There are very limited methods of relieving dyspnea that are independent of the causative disease. L-menthol olfactory stimulation is reported to be effective for dyspnea during exercise and inspiratory resistance. Therefore, we examined the effects of L-menthol olfactory stimulation on exertional dyspnea during the 6 min walking distance test (6MWT) in patients with chronic breathlessness syndrome. The subjects who consented to the study were divided into two groups. In Group A, the first 6MWT was performed as usual (placebo) while wearing a surgical mask, and the second 6MWT was performed under the L-menthol condition. In Group B, the first 6MWT was performed under the L-menthol condition, and the second 6MWT was performed as a placebo. A total of 16 subjects (70.8 ± 9.5 years) were included in the analysis. As for the effect of reducing dyspnea, a significant difference was observed in Group A patients who underwent the L-menthol condition in the second 6MWT (
