Sensitivity analysis
SENSITIVITY
Sensitivity Analysis of the primary outcomes was performed at a NED threshold of 0.2 µg/kg/min and 0.3 µg/kg/min. At a threshold of 0.2 µg/kg/min, there were only 27 patients in the low-NED AT II group and 18 patients in the low-NED placebo group. Overall, with a sample size this low, there was not enough power to detect a difference in 28-day survival between these two groups (HR 0.55; 95% CI 0.19–1.55,
