FIG. 10: The lower panels in this Figure show the outcomes of the RESCUE trial.[13] It is clear from the Kaplan-Meier curves extended over 365 days (left panel) that addition of home NIV made no difference to admission-free survival, the primary outcome of the trial. Because the trial had an extended recruitment period and required a prolonged period of observation for the study participants, longer term survival over an extended period of time could also be studied in this trial. Yet even extended out to almost 2200 days (right panel) addition of home ventilation showed no benefit on long-term outcomes.
