Distribution of performance on selected neuropsychological tests within the group of centenarians at baseline and last visit. For all neuropsychological tests, n = 40. If a test was not administered or not completed, the score was indicated as not available (N/A), set apart from the scores by a dashed line. Dots are scattered to ensure visibility of all points. Cases for which only baseline data is available (T0) are shown as black circles, cases with one (T1), two (T2) or three (T3) follow-up visit are shown as blue squares and red or green triangles respectively
