1.Primary Outcome
Title Nail Bed Clearing
Hide Description Change in amount of clear nail over time.
Time Frame 48 weeks
Hide Outcome Measure Data
Hide Analysis Population Description
There was a fatal design flaw to the trial. We were advised to collect nail samples for mycologic analysis at every visit. As a result investigators were removing our primary outcome variable, increase in clear nail, at each visit. Consequently our estimates of nail growth following treatment are inaccurate and invalid.
Arm/Group Title Treated Great Toe Untreated Great Toe
Hide Arm/Group Description:
Laser treatment of great toe
untreated control great toe
Overall Number of Participants Analyzed 0 0
No data displayed because Outcome Measure has zero total analyzed.
2.Secondary Outcome
Title Mycology
Hide Description KOH, PCR and cultures of patients who were bilaterally positive or negative for each test.
Time Frame 48 weeks
Hide Outcome Measure Data
Hide Analysis Population Description
There was a fatal design flaw to the trial. We were advised to collect nail samples for mycologic analysis at every visit. As a result investigators were removing our primary outcome variable, increase in clear nail, at each visit. Consequently our estimates of nail growth following treatment are inaccurate and invalid.
