CI confidence interval, HR hazard ratio. aAdjusted for age, sex, low income, subtypes of stroke, hypertension, diabetes, mental disorders, hyperlipidemia, cardiac arrhythmia, traumatic brain injury, Parkinson’s disease, depression, Alzheimer’s disease, obesity, malignant brain tumors, smoking cessation, rehabilitation, anticoagulant, anti-platelet agents, lipid-lowering agents, admission to intensive care unit, neurosurgery, and lengths of hospital stay. The Akaike information criterion of the full model was 85795.051; the correlation coefficient of the Schoenfeld Residual for acupuncture and time of the full model was 0.00875, and the p-value was 0.5787, or no indication of lack of fit for the model. bPer 1000 person-years
