SD = Standard Deviation, MD = Mean Difference, t = paired t-test, AOM = Automated Oscillometric Method, DHM = Doppler with Hybrid Method, SBP=Systolic Blood Pressure, DBP = Diastolic Blood Pressure, MAP = Mean Arterial Pressure, BP = Blood Pressure, Intra-class correlation coefficients (Scores <0.5 = poor agreement, 0.5 to < 0.75 = moderate agreement, 0.75-0.90 = good agreement, >0.90 = excellent agreement), p < 0.05 indicates significance,
