A Trial sequential analyses (TSA) for'comparing O2 desaturation in HFNC versus control groups'subgroup: α = 5% two-sided, β = 20%, Relative. Risk Reduction: 54.9%, Incidence in Control: 32.5%. O2: oxygen. B Trial sequential analyses (TSA) for'comparing O2 desaturation in HFNC versus control groups'subgroup: α = 5% two-sided, β = 20%, Relative. Risk Reduction: 69.07%, Incidence in Control: 33.8%. O2: oxygen
