Data are shown as and compared by analysis of variance followed by LSD -test. 24hSBP: 24-hour mean systolic blood pressure; 24hDBP: 24-hour mean diastolic blood pressure; dSBP: daytime mean systolic blood pressure; dDBP: daytime mean diastolic blood pressure; nSBP: nighttime mean systolic blood pressure; nDBP: nighttime mean diastolic blood pressure; 24hDBPSD: 24-hour dynamic blood pressure standard deviation; 24hSBPSD: 24-hour systolic blood pressure standard deviation; 24hDBPSD: 24-hour diastolic blood pressure standard deviation; dSBPSD: daytime systolic blood pressure standard deviation; dDBPSD: daytime diastolic blood pressure standard deviation; nSBPSD: nighttime systolic blood pressure standard deviation; nDBPSD: nighttime diastolic blood pressure standard deviation; 24hSBPCV: 24-hour systolic blood pressure coefficient of variation; 24hDBPCV: 24-hour diastolic blood pressure coefficient of variation; dSBPCV: daytime systolic blood pressure coefficient of variation; dDBPCV: daytime diastolic blood pressure coefficient of variation; nSBPCV: nighttime systolic blood pressure coefficient of variation; nDBPCV: nighttime diastolic blood pressure coefficient of variation. ^#, control groups vs. WML groups; , control groups vs. mild WML group and severe WML group; , control groups vs. mild WML group and severe WML group.
