The White Matter Functional Abnormalities in Patients with Transient Ischemic Attack: A Reinforcement Learning Approach

Table 1

Demographic and clinical information of all participants.

Variables	TIA ()	HCs ()	value
Age (year, )			0.182^t
Sex (male/female)	37/11	30/11	0.670^χ
Systolic blood pressure (mmHg, )		^a	<0.001^t
Diastolic blood pressure (mmHg, )		^a	0.007^t
Blood sugar level (mmol/L, )		^a	0.001^t
Total cholesterol (mmol/L, )		^a	0.045^t
Triglycerides (mmol/L, )		^a	0.213^t
HDL-C (mmol/L, )		^a	0.306^t
LDL-C (mmol/L, )		^a	0.004^t
ABCD2 scores (median)	4 (2–6)
Smoking, no. (%)	31 (64.58%)
Drinking, no. (%)	20 (41.67%)
Hypertension, no. (%)	22 (45.83%)
Diabetes, no. (%)	8 (16.67%)
Coronary artery disease, no. (%)	2 (4.17%)
Atrial fibrillation, no. (%)	1 (2.08%)
Medication, no. (%)	—
Antiplatelets, no. (%)	48 (100%)
Statins, no. (%)	2 (4.17%)
DWI hyperintensity, no. (%)	6 (12.50%)
Vessel stenosis, no. (%)	9 (18.75%)
TIA/stroke attack in one year follow-up, no. (%)	12 (27.27%)^b

Note: ^t The P value was obtained by Student’s t-test; ^χ The P value was obtained by two-tailed Pearson chi-square t-test; ^a Data were missing for 6 controls; ^b Four patients dropped out in the one-year follow-up; ABCD2 is a simple score to identify individuals at high early-risk of stroke after a TIA. TIA: transient ischemic attack; HCs: healthy controls; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol.
