†Treatment related, as defined by each trial.
‡Trials contributing data for analyses of haematoma growth at 24 hours: INTERACT1&2, ICH-ADAPT, ATACH-II, FAST-MAG.
§Model adjusted for age, sex, baseline haematoma volume and time from symptom onset to randomisation.
CI, confidence interval; mRS, modified Rankin Scale; OR, odds ratio; SAE, serious adverse event.
