Impairment in Preattentive Processing among Patients with Hypertension Revealed by Visual Mismatch Negativity

Table 2

Mean and standard deviation of accuracy rates and reaction times for the hypertensive patients and normal controls.

	Hypertensive patients	Normal controls	𝑃 value
RT (ms), mean (SD)	330.22 (49.02)	335.22 (30.57)	0.74
ACC (%), mean (SD)	98.56 (2.62)	99.24 (1.78)	0.41

P value is for test of difference between hypertensive patients and normal controls.
SD: standard deviation; ACC: accuracy rates; RT: reaction times.
