CRP and delirium: In delirious patients, laboratory tests tended toward neutrophilia (with delirium 8.5 ± 5.4 × 103/dL, 6.6 ± 4.0 × 103/dL without, p = 0.0011), lymphopenia (with delirium 1.3 ± 1.0 × 103/dL, 1.6 ± 1.3 × 103/dL, p = 0.0199), increased urea (with delirium 64.5 ± 33.7 mg/dL, 55.6 ± 35.8 mg/dL without, p = 0.0055) and increased CRP (with delirium 7.0 ± 7.9 mg/L, 3.5 ± 5.8 mg/L without, p < 0.0001).
