SCORING SYSTEM:
Calculation of the mean according to 83/467/EEC criteria of July 29th, 1983; for calculation of the means of erythema and edema only the readings of 24, 48, and 72 hours are used
EVALUATION OF ERYTHEMA (R) AND EDEMA (ED) :
0 = NONE
1 = VERY SLIGHT
2 = WELL-DEFINED
3 = MODERATE TO SEVERE
4 = SEVERE TO VERY SEVERE
