Example dataset


The Awakening and Breathing Controlled (ABC) trial randomized critically ill patients receiving mechanical ventilation 1:1 within each study site to management with a paired sedation plus ventilator weaning protocol involving daily interruption of sedative through spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs) or sedation per usual care (UC) and SBTs.

The example dataset is from a single site substudy in ABC. The researchers assessed differences in cognitive, psychological and functional outcomes at 3 and 12 months after randomization.


A dataframe with 5 variables:




Treatment assignment. 0: UC + SBT, 1: SAT + SBT


Survival days


Cognitive score at 12 months


Cognitive score at 3 months
