Effect of Menthol on Dyspnea During Exercise in Individuals With COPD.

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
Objective: To investigate the effects of olfactory stimulation with menthol on exertional dyspnea and physiological data during cycling exercise in patients with chronic obstructive pulmonary disease (COPD). Design: Controlled trial. Patients with COPD hospitalized for pulmonary rehabilitation performed endurance exercise training using a cycle ergometer and resistance training with and without menthol to decrease respiratory sensations. Setting: Three exercise sessions on a cycle ergometer. Participants: Twenty-one adult patients (N=21; women; mean age ± SD, 64±8y; Global Initiative for Chronic Obstructive Lung Disease (GOLD) score IV) referred for pulmonary rehabilitation with functional chronic dyspnea (rated ≥2 on the modified Medical Research Council scale) were included. Interventions: Session 1 without menthol, session 2 with menthol, and session 3 without menthol. Main Outcome Measures: The primary evaluation criterion was the maximum dyspnea experienced during the sessions on a cycle ergometer. Several parameters were recorded and analyzed, including oxygen saturation, heart rate, muscle fatigue (assessed using the modified Borg scale), and dyspnea, as well as the duration of exercise, power output, and distance covered on the cycle ergometer. After completing the sessions, patients were asked about their preference regarding the use of menthol (with or without). Results: Three types of patients were identified based on dyspnea during exercise: responders (n=7; 33%), partial responders (n=7; 33%), and nonresponders (n=7; 33%). The comparison between responders and nonresponders showed a significant difference regarding the oxygen flow rate during effort (2.5 [0.0-3.0] vs 0.0 [0.0-0.8] l/min; Conclusions: Menthol could be an adjuvant to exercise rehabilitation, improving exercise-induced dyspnea in patients with chronic dyspnea, particularly in patients with high oxygen flow during exercise.
