Outcome Measures

Primary Outcomes (1)

  • CLR-transformed Abundance of Any Significant Taxa

    The primary outcome measures the relative abundance of Kingella after treatment with Altreno in acne patients vs without treatment in healthy subjects. The relative abundance was represented as centered log ratio (CLR) transformation. These values are all relative terms centered around 0, more negative means less abundant in comparison. More positive means more abundant in comparison.

    Baseline, 90 days after treatment, and followed by 30 days of no treatment
