Table 1.

Age, sex, and mini-mental state examination (MMSE) in idiopathic normal pressure hydrocephalus (iNPH), subcortical small vessel disease (SSVD), and controls.

	iNPH n = 52	SSVD n = 17	Controls n = 28
Age, median (IQR)	72 (68–79)#	72 (66–76)	67 (66–71)
Female, n (%)	23 (44 %)	12 (71 %)	10 (36 %)
MMSE, median (IQR)	24 (22–27) ###	27 (25–28)&&&	30 (29–30)

Age in years and mini-mental state examination (MMSE) are presented as median and interquartile range (IQR). Significance testing was made by Wilcoxon-Mann-Whitney U-test and shown as

^# p < 0.05,

^### p < 0.001 (iNPH vs. controls),

^&&&p < 0.001 (SSVD vs. controls).
