Brain tissue oxygen pressure combined with intracranial pressure monitoring may improve clinical outcomes for patients with severe traumatic brain injury: a systemic review and meta-analysis.

Secondary outcomes A total of 10 studies (four RCTs and six NRCTs) reported the in-hospital mortality, the use of combined PbtO 2 and ICP monitoring may reduce the in-hospital mortality, but this did not reach statistical significance (RR 0.81, 95% CI [0.66–1.01], P = 0.06, I 2 = 32%, Fig. 3A ).
