Preoxygenation before intubation in adult patients with acute hypoxemic respiratory failure: a network meta-analysis of randomized trials

Table 3 The P-score statistics

	HFNC and NIV	NIV	HFNC	COT
Lowest SpO₂ during intubation	0.895	0.739	0.336	0.030
SpO₂ < 80% during intubation	0.957	0.634	0.344	0.066
Intubation-related complications	0.560	0.774	0.595	0.071
Mortality	0.689	0.556	0.598	0.157

P-scores represent the extent of certainty that a treatment is better than the other treatments—the P-score would be close to 1 when a treatment is certain to be the best and close to 0 when a treatment is certain to be the worst
