^*A score of zero indicates that no spot sign is identified in the CT angiogram.

^†Length of hospital stay among the 393 survivors.

^‡Modified Rankin Scale at 3-month follow-up.

^§Defined as a modified Rankin Scale of ≥4 at 3-month follow-up among the 393 survivors.

ICH: intracerebral hemorrhage; LOS: length of hospital stay; mRS: modified Rankin Scale; n: number of patients within spot sign score group in the entire cohort; ns: number of patients within spot sign score group among survivors; AUC: area under the curve after receiver operating characteristic analysis; CI: confidence interval; n/a: not applicable.
