Figure 2

Driving performance and results from tests including TMT. Open dots correspond to each individual observation, grey blocks’ upper borders correspond to mean observed TMT duration on a log scale. Interval bars represent 95% CI. P-values correspond to F statistics comparing poor drivers to excellent drivers. For figures A &B, doted lines represent the threshold (TMT-A ≥54 sec; TMT-B ≥150 sec) from which TMT duration can evoke unfitness to drive. For figure C, doted lines represent threshold of the MoCA to differentiate drivers without cognitive impairment (NoCI), those with mild cognitive impairment (MCI), and those with severe cognitive impairment (SCI).
