Results are obtained from intra-arterially determined
brachial pressure and from noninvasively measured pressure
for comparison. Thirty-minute averages were calculated
for all indices. The effect of morning rising was
evaluated by comparing 10 30-min averages before
(12:30–05:00, night) and after rising (08:30–13:00, morning).
Although awaking was at 06:00 according to the
protocol, some uncertainty exists whether or not all patients
awoke/rose at exactly that time. Therefore, the period
between 05:30 and 08:00 was not included in the analysis,
comparable to practice in the analysis of the morning blood
pressure surge [24].
