Source & limitations
The source displays “12 responses” for this profile. This is not a confirmed participant count or a denominator for individual questions.
- Voluntary self-reports from Pep-Pedia visitors; identity, treatment, outcomes and timing are unverified. These data are not efficacy or safety estimates.
- The source displays a profile-wide response label, not a confirmed unique participant count. It stays unchanged across questions. Question-specific denominators and absolute option counts are not exposed.
- Only the top five categories are displayed for some questions. Extra categories are retained as an undisplayed-category count; their labels and percentages are unavailable.
- Displayed percentages are rounded. They may not total 100%, especially where categories are hidden.
- This is a dated snapshot, not a live survey or current recommendation.
