Methods, limitations & source review
Study limitations
- Small proceedings report; numerical between-side effect sizes, uncertainty, registration and complete methods require verification.
- A nominal serum concentration does not establish the exact copper species or delivered exposure; eyebrow results do not establish scalp regrowth or systemic safety.
Publication counts are not counts of independent trials. Reviews, translations and reports sharing participants may overlap. Findings apply to the studied preparation, population and endpoints.
