* this table refers to group comparisons and the association was reported with the group with the highest extent of technology use, the group after automation, or the group with the highest level of mental tasks
** number of papers represented by the counts: see Fig. 3
*** summary assessment independent of underlying construct; significant negative/significant positive = if 75% of reported associations are significant negative/significant positive and the rest is not significant; all other combinations: inconclusive; not significant = no significant association at all
