Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Visual Discomfort | Each minute from minutes 2 through 8 of each light exposure | Participants reported their visual discomfort using an 11-point numeric rating scale ranging from 0 (no discomfort) to 10 (extreme discomfort). The primary visual discomfort outcome was the mean of the seven ratings collected at minutes 2-8. |
| Secondary | Digit Symbol Substitution Test | Minute 8 after onset of light exposure | Digit Symbol Substitution Test performance was analyzed as the raw number of correctly completed items. |
| Secondary | Headache Intensity | Minute 8 after onset of light exposure | Participants reported headache intensity using an 11-point numeric rating scale ranging from 0 (no pain) to 10 (extreme pain). The primary headache intensity outcome was the change in headache intensity, calculated as headache intensity after light exposure minus headache intensity prior to light exposure. |
| Secondary | Pupil Size | At end of 10-minute light exposure | The primary pupillary outcome was mean bilateral pupil diameter, calculated as the mean of the right eye and left eye measurements. |
