-
aHHS scores are categorized as >90 excellent; 80-89 good; 79-79 fair and <70 bad [16, 29]. We defined a clinically relevant improvement as one category improvement
-
bOHS scores are categorized as > 41 excellent, 34 -41 good, 27-33 fair, <27 bad [30, 31]. We defined a clinically relevant improvement as one category improvement
-
cWe used a difference of 20Â mm or more as clinically relevant improvement [34]
