"leicht" +: considered as equivalent to Grade 2 according to OECD Guideline 405
"stark" ++: considered as equivalent to Grade 3 effect according to OECD Guideline 405
"sehr stark" +++: considered as equivalent to Grade 4 according to OECD Guideline 405
Grading system for conjunctivae:
"reizlos" Ø: considered as equivalent to Grade 0 according to OECD Guideline 405
"leicht" +: considered as equivalent to Grade 1 according to OECD Guideline 405
"stark" ++: considered as equivalent to Grade 2 effect according to OECD Guideline 405
"sehr stark" +++: considered as equivalent to Grade 3 according to OECD Guideline 405
