PRIMARY outcome

Timeframe: At the end of 1 menstrual period (up to 10 days) for each intervention

Population: All subjects who have no major protocol deviations and return at least 1 tampon that can be assessed for elongation.

The percentage of used tampons within each test code that have elongated \>10mm. The denominator for the percentage calculation is based upon the number of used tampons returned within each test code.

SECONDARY outcome

Timeframe: At baseline, prior to any interventions

Population: All subjects randomized into the study and the gynecological exam subset. Packaging interview was conducted at the baseline visit, independent of and prior to any intervention. Therefore, results are broken out by study arm. Responses for some questions were not recorded for all subjects due to protocol deviations.

Proportion of participants able to locate key packaging/labeling information.
