The SCORAD index : Total score

  1. How is it calculated ?

  2. How was it validated
    Based on 88 cases from 5 centers, criteria were weighted using the mathematical model of main component analysis.
    It was thus determined that intensity represents around 60 %, soread 20 % and subjective signs 20 % of the total score.

  3. How reproducible is it ?
    In the photo, the variation in intraindividual assessment is slight.
    Thus, for two slides showing the same degree of severity, the probability of inclusion in the same class is greater than 70 %.

  4. What is its distribution ?
    Two measurement systems were tested and corelated. The system with the more normal distribution was chosen.
