Outcome results

Primary

Tolerance of Tampon Wear Via Physician Assessment of Vaginal Health

The physician examiner determined tampon tolerance based on the following: 1) Vaginal erythema (0-4 scale), 2) vaginal lacerations (presence or absence), 3) vaginal abrasions (presence or absence), 4) vaginal pH, 5) vaginal discharge

Time frame: within 72 hours last tampon use

Population: ITT population was the primary population of analysis. The ITT population was defined as those participants who were randomized, received at least one test product and had at least one post-product use measurement.
