Similarly, those with a normal baseline P2/P1 ratio and intact skull ( n = 15) or craniotomy/fracture ( n = 11) presented an increase in the P2/P1 ratio during IJVC (mean difference 0.10, 95% IC 0.05–0.16, p = 0.001), but not those with craniectomy ( n = 6; mean difference 0.03, 95% IC −0.02–0.08, p = 0.134), although the interaction did not reach statistical significance ( p = 0.425).
