P-values are calculated using paired t-tests and will only include participants who had responses for the mentioned questions at both visits.

^aThis is the average of average individual behaviour scores. The average individual behaviour score was calculated by the sum of all behaviour scores divided by the number of behavioural questions to which that individual responded.
