Table 5 Presenting the n for all the different analysed pairs at different RASS levels. In the first group (Table 2) are the pairs of RASS and the analysed variables from before the RASS assessment presented in Table 2, including Bispectral Index (BIS), frontal EMG, Responsiveness Index (RI), and Averaged Blood pressure Variability (ARV). In the second group (Table 3) are the BIS/RI and RASS pairs presented in Table 3, grouped into low and high EMG and ARV groups. In the final group (Table 4) are the stimulus–response pairs presented in Table 4, which represent the pairing of a painful stimulus and measured variable values following stimulation. For the Table 4 Stimulus–response pairs, RASS ≥ -2 were pooled**
