The RECOVERY-RS trial was an adaptive randomized controlled trial that was essentially conducted as 2 separate trials that compared NIV and HFNC oxygen to the same conventional oxygen therapy control group.8 The trial was stopped early and enrolled fewer than a third of the planned sample size of 4,002 participants.
