Trial Outcomes & Findings for Evaluation of 1440nm Laser Assisted Selective Photothermolysis for Treatment of Axillary Hyperhidrosis (NCT NCT02100072)

NCT ID: NCT02100072

Last Updated: 2021-01-08

Results Overview

A gravimetry test was performed to determine the quantity of sweat produced, comparing the post-treatment to the baseline numbers. A pre-weighted filter paper was placed on the armpit, and then weighed afterwards to determine the quantity of sweat produced. To calculate the change between the baseline and 3 months post baselines, the values taken at these 2 time points are subtracted from each other. A negative value means that there has been a decrease in gravimetric weight since the baseline.

PRIMARY outcome

Timeframe: Baseline and 3 months post baseline

Population: 1 subject was incapable of attending the follow up visit, so their gravimetric measurement was not able to be obtained. They were able to answer other follow up questions via the phone, however.

A gravimetry test was performed to determine the quantity of sweat produced, comparing the post-treatment to the baseline numbers. A pre-weighted filter paper was placed on the armpit, and then weighed afterwards to determine the quantity of sweat produced. To calculate the change between the baseline and 3 months post baselines, the values taken at these 2 time points are subtracted from each other. A negative value means that there has been a decrease in gravimetric weight since the baseline.
