FIGURE 3.

Risk of clinical progression and probability of oxygen weaning by randomisation arm. a) Intention-to-treat analysis for risk of clinical progression, defined as death, mechanical ventilation, need for high-flow nasal cannula (HFNC) or noninvasive ventilation with continuous positive airway pressure (CPAP). b) Intention-to-treat analysis for probability of oxygen discontinuation by randomisation arm. c) As-treated analysis for risk of clinical progression, defined as death, mechanical ventilation, need for HFNC or noninvasive ventilation with CPAP. d) As-treated analysis for probability of oxygen discontinuation by randomisation arm. The continuous line represents the control group, the dashed line represents the prone positioning group.
