Open or close this module Outcome Measures
Primary Outcome Measures:
1. Clinical clearance after 1 week of treatment
1 week
Secondary Outcome Measures:
2. time to clinical clearance
1 week
3. score in the 6-point grading system

The 6-point grading system will assess clinical response based on each of the following six paramaters. One point will be assigned for each of the following parameters present in a patient, with the maximum possible score on this grading system being 6. A patient need not satisfy all six parameters. A decrease in score on this grading system compared to baseline will indicate clinical improvement, while an increase in score will indicate clinical worsening.

  • erythema
  • edema
  • vesiculation
  • pustulation
  • crusting
  • scaling

[Time Frame: 1 week]
4. change in size of lesion compared to baseline
1 week
5. presence or absence of recurrence on any part of the body 2 weeks after starting treatment
1 week
6. presence or absence of adverse events during treatment
1 week
