^aNumbers for oxygen and control groups, respectively;

^bodds ratio (reference category is oxygen);

^cmean difference (control–oxygen); CI = confidence interval.

Higher scores on the modified Rankin scale and on the Nottingham Extended Activities of Daily Living (NEADL) Scale are worse; higher scores on the Barthel Index and EuroQol are better.
