Table 7.

Separation of intervention groups in terms of arterial partial pressure of oxygen for recent trials of conservative oxygen therapy.

Trial	Intervention group	Target SpO₂	Median PaO₂ (kPa)	Group PaO₂ separation (kPa)
This study (Martin et al.)	Conservative O₂	88–92%	8.6	3.2
This study (Martin et al.)	Control	Usual care	11.8	3.2
Girardis et al.⁶	Conservative O₂	94–98%	11.6	2.0
Girardis et al.⁶	Control	Usual care	13.6	2.0
Mackle et al.⁷	Conservative O₂	91–96%	10.9^a	1.6
Mackle et al.⁷	Control	≥91%	12.5^a	1.6
Barrot et al.⁸	Conservative O₂	88–92%	9.3^a	4.6
Barrot et al.⁸	Control	≥96%	13.9^a	4.6

Median PaO₂ and group separation in controlled trials of conservative oxygen therapy in Critical Care settings. The values for means for Mackle et al and Barrot et al’s studies were estimated from graphs in supplemental appendices provided with the manuscripts.
