^aGlobal composite score is the average of the z-scores of the TICS, delayed recall of the TICS 10-word list, immediate and delayed recalls of the East Boston Memory Test, category fluency and digit span backward

^bAll models are multivariable-adjusted as indicated in footnote c of Table 3

^cScore defined as the number of positive response(s) among seven items: change in memory, difficulties in remembering a short list of items, difficulties in remembering things from one second to the next, difficulties in remembering recent events, difficulties in understanding instructions, difficulties in following a conversation, difficulties in finding the way around familiar streets; in our sample, ‘1’ is the median score

^dTest for linear trend using the ordinal score on categories of QOL change at retirement
