Fig. 3From: Novel insights on association and reactivity of Bispectral Index, frontal electromyogram, and autonomic responses in nociception-sedation monitoring of critical care patientsViolin plot diagrams (black boxes for quartiles, green circles for median values, envelopes presenting distribution) of the BIS, EMG and ARV responses to stressful stimuli at varying RASS levels. The ∆ values are derived by subtracting the prestimulus value from the poststimulus valueBack to article page
