Abstract

fetched live from OpenAlex

<b><i>Background:</i></b> Recently, low-dose oral minoxidil (LDOM) has entered the landscape of therapies for androgenetic alopecia (AGA). We determined whether using LDOM is associated with improving AGA in a dose-dependent manner; secondarily, we examined whether a dose-dependent association also exists for safety. <b><i>Methods:</i></b> Systematic searches were conducted in PubMed and Scopus to identify studies that would be eligible for our quantitative analyses; the logistics of our analyses was determined by the data we gathered. <b><i>Results:</i></b> Six studies were eligible for quantitative analyses; we conducted meta-regressions. We found that, for persons with AGA, increasing the dosage of LDOM by 1 mg/day was – after six months – significantly associated with an expected sex-adjusted increase in hair diameter (mean difference = 1.4 μm, <i>p</i> = 0.01), total hair density (mean difference = 47.1 hairs/cm<sup>2</sup>, <i>p</i> = 0.007), terminal hair density (mean difference = 9.1 hairs/cm<sup>2</sup>, <i>p</i> = 0.001), risk of hypertrichosis (mean difference = 17.9%, <i>p</i> = 0.006), and cardiovascular adverse events (mean difference = 4.8%, <i>p</i> = 0.004). <b><i>Conclusions:</i></b> Our study produced new evidence as our work is the first to show a positive dose-dependent association between the use of LDOM and change in hair diameter, hair density, risk of hypertrichosis, and cardiovascular adverse events for persons with AGA. Future randomized trials could produce causal evidence that would corroborate these dose-dependent associations.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
