Fig. 2

Individual-trajectory plot of sedation status, vital status, or tracheostomy status during their ICU stay. In this figure, we plot individual daily trajectories of sedation status (deep in dark blue, moderate in blue, adequate in light blue, agitated in pink), vital status (death before 28 days in red, achieved unassisted breathing by 28 days and alive in navy blue), and if the participant received a tracheostomy (in green) using a Causa plot (see Additional file 1). Our categorization of sedation is based on the Richmond Agitation Sedation Scale score (RASS), and if unavailable, it is based on a conversion based on the Ramsay Scale score or the Glasgow Coma Scale score to RASS as shown in Additional file 1: Table S2. Each row represents a study participant, and each column represents an ICU day between enrollment and day 28. We stratified the rows by vital status or if the participant was alive at 28 days but received unassisted breathing. If the patient was neither dead nor receiving unassisted breathing, they were shown as the “Neither” category by 28 days, which includes patients that were still intubated or that had a tracheostomy
