Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Depigmentation of melasma lesions by Colorimetry | 12 weeks | Quantification of the colour change in the melasma lesions by means of the L axis of the CIE system. 0 is pure white, 100 y total dark. |
| Secondary | Global Physician Assessment | 12 weeks | Clinical improvement is assessed by means of digital photographic registration (frontal, right, and left views). An independent observer clinically graded the global improvement as poor (0-25%), mild (26-50%), good (51-75%), and excellent (\>75%). |
| Secondary | MASI (Melasma Area Severity Index) | 12 weeks | The total score would range from 0-24, involving the forehead (30%), right malar (30%), left malar (30%) and chin (10%), and using area of involvement (0=absent, 1=\<10%, 2=10%-29%, 3=30%-49%, 4=50%-69%, 5=70%-89% and 6=90%-100%) and darkness (0=absent, 1=slight, 2=mild, 3=marked and 4=severe). Computation would be as follows: 0.3 A(f) D(f) + 0.3 A(lm) D(lm) + 0.3 A(rm) D(rm) + 0.1 A(c) D(c). |
| Secondary | Melanin content by Fontana Masson stain | 12 weeks | The Fontana-Masson Stain is specific for melanin, this histochemical reaction reveals accumulations of black material wherever melanin is located. A skin biopsy of lesions will be taken initially and at the end of study. The melanin content will be quantified by a software image analysis of the slides. |
