Table 2 Cumulative burden of abnormal Neurological Pupil index (NPi < 3) is associated with the severity of intracranial hypertension and 6-month Glasgow Outcome Score (GOS)
Intracranial hypertension (ICHT) | No ICHT (N = 22) | Non-refractory ICHT (N = 15) | Refractory ICHT (N = 17) | p value |
 % measurements with abnormal NPi < 3 | 0.5 (0–11) | 1 (0–9) | 38 (3–96) | 0.007* |
6-month Glasgow Outcome Score (GOS)** | GOS 4–5 (N = 18) | GOS 1–3 (N = 31) | p value | |
 % measurements with abnormal NPi < 3 | 0 (0–7) | 15 (1–80) | 0.002 | |
