Mean group differences in cognitive functioning for body mass and BP groups

BMI (kg/m²)	Cognitive score for normal BP	Cognitive score for high BP	F
< 18.5	12.59 (n = 22)^a	17.80 (n = 5)	1.09
18.5–24.9	19.25 (n = 73)	20.38 (n = 48)	0.48
25–29.9	21.43 (n = 30)	21.80 (n = 39)^b	0.87
≥ 30	15.88 (n = 8)	20.67 (n = 12)	1.79

Total N = 237. Means with different superscripts are significantly different. F: F-test; ^a lowest group; ^b highest group
