Correlation matrix of spatial navigation performance and CSF biomarkers.

	Route-repetition task (% correct)	Route-retracing task (% correct)	Directional-approach task (% correct)
Amyloid-β1–42 (pg/ml)	0.425**	0.234	0.310*
Total tau (pg/ml)	−0.212	−0.290	−0.307*
P-tau181 (pg/ml)	−0.203	−0.296*	−0.329*

*Correlation (uncorrected) is significant at the 0.05 level (2-tailed), **Correlation (uncorrected) is significant at the 0.01 level (2-tailed). Key: CSF, cerebrospinal fluid; p-tau₁₈₁, phosphorylated tau₁₈₁.
