Correlations between performance on RTT and cognitive test performance.

	Performance on RTT
	Total correct answers	Total execution time
MMSE	r = 0.344 (p = 0.003)∗	r = −0.102 (p = 0.392)
SVF	r = 0.157 (p = 0.186)	r = −0.114 (p = 0.336)
DS-DO	r = 0.308 (p = 0.008)∗	r = −0.089 (p = 0.456)
DS-RO	r = 0.400 (p = 0.005)∗	r = −0.022 (p = 0.853)

MMSE = Mini-Mental State Examination; SVF = semantic verbal fluency; DS-DO = digit span in direct order; DS-RO = digit span in reverse order.
