Fig. 4From: Development of an algorithm using clinical tests to avoid post-operative residual neuromuscular blockRegression analysis with classification and regression tree (CART). The upper section of the figure depicts how CART revealed six nodes of test scores that significantly divide the collective regarding the TOFR measured by calibrated electromyography (EMG). The lower section of the figure shows boxplots of EMG measured TOFR in patients allocated to the respective nodes. The test combinations of node 11 (arm lift ā„5Ā s, head lift ā„5Ā s, and swallowing without any hindrance) was able to discriminate between patients with TOFR <0.7 and TOFR ā„0.7Back to article page
