Cut-off

#1
I am reading an article where 5 has been set as a cut-off score. No > or >= symbols are given, and I don't know whether a score of 5 would identify someone as a case or not (I know that anyone with a score above 5 is considered a case and someone with a score below 5 is not. Is there a commonly accepted interpretation for this type of information, or does the given information not say whether someone with an exact score of 5 is a case or not?
