Na/K ratio comparisons between VaD and AD.

Class	Na (mmol/kg)	K (mmol/kg)	Na/K ratio	p-value
Dry-weight hippocampal tissue in VaD, this study
Control	471 (403–538)	321 (291–351)	1.49	0.031
VaD	609 (495–722)	304 (273–336)	2.03
Wet-weight hippocampal tissue in VaD, this study
Control	78 (72–85)	56 (51–61)	1.43	0.005
VaD	97 (87–107)	47 (42–52)	2.15
Dry-weight hippocampal tissue in AD, Xu et al. (2017)
Control	389 (321–458)	323 (301–345)	1.2	0.001
AD	595 (525–664)	321 (263–379)	1.92

Data are means (± 95% CI); p-values for significance of between-group differences were calculated by Welch’s t-tests based on measurements from control (n = 10) and VaD (n = 10)/control (n = 8) and AD (n = 9) brains.
