Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | E-cigarette Dependence | Baseline for demographic data. | E-cigarette dependence will be assessed using the Penn State Electronic Cigarette Dependence Index, adapted by Sornsenee et al. (2025). The questionnaire consists of 10 items, with a maximum total score of 20. Scores are interpreted as follows: 0-3 indicates no e-cigarette dependence, 4-8 indicates low dependence, 9-12 indicates moderate dependence, and 13 or higher indicates high dependence. |
| Primary | Nicotine Withdrawal Symptoms | Immediately before and immediately after each breathing intervention session. | Nicotine withdrawal symptoms will be assessed using the Thai version of the Minnesota Nicotine Withdrawal Scale-Revised (MNWS) (Hughes \& Hatsukami, 2008), translated by Sirirat Kanokururot and Sunida Preechawong (2010). This self-report questionnaire measures the perceived severity of nicotine withdrawal symptoms. It consists of 9 items rated on a 5-point scale ranging from 0 (no symptoms) to 4 (severe symptoms). The total score ranges from 0 to 36, with a score of 0 indicating no nicotine withdrawal symptoms and a score of 36 indicating the most severe nicotine withdrawal symptoms. |
| Secondary | Fractional Exhaled Nitric Oxide (FeNO) | Immediately before and immediately after each breathing intervention session. | FeNO will be measured using a device equipped with a bacterial filter and mouthpiece. Participants will place their lips around the mouthpiece and exhale into the device for 6 seconds while maintaining the indicator ball within the designated range. Results will be recorded in parts per million (ppm). |
| Secondary | Peak Nasal Inspiratory Flow (PNIF) | Immediately before and immediately after each breathing intervention session. | Peak nasal inspiratory flow will be measured using a peak nasal inspiratory flow meter. Participants will perform the breathing maneuver according to the study procedure, and the measurement will be recorded in liters per second (L/s). |
