First preinduction mean arterial pressure versus mean daytime mean arterial pressure
Histogram showing the frequency (n; y axis; n total = 361) of the differences between the first preinduction MAP and the mean daytime MAP. The median difference (25th and 75th percentile) was -1 (-8 and +8) mmHg (p <0.001). The dotted vertical line represents the median difference.
