Legend. Raw score, score test; Adjusted score: obtained by subtracting or adding the contribution of patient’s age and education; Equivalent score: adjusted scores converted to a five-point interval scale, ranging from 0 to 4 equivalent scores. Score 0 was equal or lower than the outer tolerance limit (5%), NP, not performable
