Figure 2: Changes in mean arterial pressure in both groups. Markers represent mean. Error bars represent SEM. P ≤ 0.05 was considered statistically signifi cant. At 15 min (T5), Pvalue was 0.027; at 20 min (T6), Pvalue was 0.045, at 25 min (T7), Pvalue was 0.047; and at 35 min (T9), Pvalue was 0.007. P ≤ 0.001 was considered highly statistically signifi cant; at 40 min (T10), Pvalue was <0.0 01.
