- Data are presented as median (range), number (percent), or odds ratio (95%). Categorical variables are presented with each state on a separate row. The odds ratio represents the odds of survival when the first state (first row) is present compared to when the second state (second row) is present. *Calculated for 187 patients with measurable haemodynamic response. Normal (within 20% of baseline blood pressure), Abnormal (not within 20% of baseline blood pressure). Bold values indicate P <0.05. ES, etomidate suxamethonium; FKR, fentanyl ketamine rocuronium.
