Mean 1 and Mean 2 are average of scores from lower and upper 50th percentiles, respectively.
Mean 1 and Mean 2 are average of scores from 2nd and 3rd quartiles, respectively.
Mean 1 and Mean 2 are average of scores from all subjects for “endobronchial intubation” and “unstable bradycardia” emergency scenarios, respectively.
Calculated as difference divided by average of means multiplied by 100.
Calculated as difference divided by pooled standard deviation from all 20 subject scores.
