SCORING SYSTEM:
Observed effects: observed were the parameters erythema, edema, scaling, and necrosis
Grading system for redness and edema: The data reported have to be converted into presently used numerical grading system as given in the following table
"reizlos" (no symptom) Ø, "fraglich" (questionable) (+): considered as equivalent to grade 0 (no irritating effect) according to OECD Draize scheme
"leicht" (slight) +: considered as equivalent to grade 1 (very slight effect) according to OECD Draize scheme
"stark" (marked) ++: considered as equivalent to grade 2 (well-defined effect) effect according to OECD Draize scheme
"sehr stark" (severe) +++: considered as equivalent to grade ≥3 (severe effect) according to OECD Draize scheme
