1 Mini Mental State Examination [29]: The MMSE comprises 11 main questions with a maximum score of 30 points. Higher scores indicate better cognitive status. A score of 23 or less indicates a lack of capacity to provide informed consent for research purposes.

2 Components of EuroQol © [31]: The EQ-5D comprises five questions on mobility, self care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem). A summary index with a maximum score of 1 can be derived from these five dimensions by conversion with a table of scores. The maximum score of 1 indicates the best health state, by contrast with the scores of individual questions, where higher scores indicate more severe or frequent problems. The visual analogue scale (VAS) indicates general health status with 100 indicating the best health status.
