  1. * Intraclass correlation coefficient (ICC) between face-to-face Sum of boxes of the clinical dementia rating scale (CDR-SB) and CDR-SB evaluated with the patient’s medical record
  2. †Case A: all the information available in the patient’s medical record is used by the evaluator to assess the CDR-SB
  3. Case B: all the information in the patient’s medical record, except the comprehensive neuropsychological assessment is used by the evaluator to assess the CDR-SB
  4. Case C: all the information in the patient’s medical record, except the comprehensive neuropsychological assessment and the medical doctor’s clinical examination, is used by the evaluator to assess the CDR-SB
