What researchers measure

Primary outcomes

  1. Percentage of Photographs Identified Accurately

    3 trained blinded evaluators were asked to pick the post treatment photo from pre and post treatment photograph sets.

    Time frame: 3 Month Follow Up

  2. Percentage of Photographs Identified Accurately

    3 trained blinded evaluators were asked to pick the post treatment photo from pre and post treatment photograph sets.

    Time frame: 6 Month Follow Up

Secondary outcomes

  1. Number of Participants With Changed and Unchanged Glands on Biopsy Sampling

    Hematoxylin and eosin (H\&E) staining was performed on all pre and post treatment biopsy samples and evaluated by a pathologist to determine if there was any change in the subjects' glands at baseline vs. post last treatment. Changes in glands are characterized by reduction in quantity and size, in addition to changes in shape.

    Time frame: up to 3 months post last treatment
