GNE and delirium: Multivariable analysis with backward selection revealed that old age (OR, 1.149; 95% CI, 1.037–1.273; P = 0.008), HTN (OR, 8.651; 95% CI, 1.332–56.163; P = 0.024), mechanical ventilator support (OR, 226.215; 95% CI, 15.780–3243.330; P < 0.001), NM blocker use (OR, 0.037; 95% CI, 0.002–0.765; P<0.033) and length of stay in the ICU (OR, 30.295; 95% CI, 2.539–361.406; P = 0.007) were risk factors for delirium (Table 3).
