This table shows the baseline characteristics of patients with isolated-LICH. Data are counts (n) and percentages (%), means and SD, or medians and IQRs. Poor outcome was considered to be a discharge modified Rankin Scale score >2.

GRE, gradient echo sequences; LICH, lobar intracerebral haemorrhage; LVH, left ventricular hypertrophy; SCr, serum creatinine; SWAN, susceptibility-weighted angiography; SWI, susceptibility weighted imaging.
