Scope: ICH Score points: GCS 3–4 = 2, 5–12 = 1, 13–15 = 0; ICH volume ≥30 cm³ = 1; intraventricular haemorrhage = 1; infratentorial origin = 1; age ≥80 years = 1 (total 0–6). 30-day mortality in the derivation cohort: 0 points 0% (0/26), 1 13%, 2 26%, 3 72%, 4 97%, 5 100% (6/6); no patient scored 6 (mortality estimated at 100%).
