Table 2.
Occurrence of presenting clinical symptoms in anterior circulation stroke (ACS) and posterior circulation stroke (PCS) patients.
| Clinical Symptom | Circulation | p | |
|---|---|---|---|
| ACS (N = 707) | PCS (N = 102) | ||

| Drooping of the mouth corner (N VII) | 588 (83.17) | 37 (36.27) | <0.0001 |
| Speech difficulties (SPEECH) | 593 (83.88) | 61 (59.8) | <0.0001 |

| HEADACHE | 0 (0) | 18 (17.65) | N/A |
| Nausea and/or vomiting (VOMIT) | 1 (0.14) | 37 (36.27) | N/A |
| Loss of consciousness (COMA) | 9 (1.27) | 20 (19.61) | N/A |
Data are N (%). Symptoms with sufficient frequencies (occurrences) were statistically compared by a chi-square test of independence between ACS and PCS; all p-values (two-sided alternative hypothesis) are reported after Benjamini-Hochberg correction; ACS, anterior circulation stroke; N, number of patients; N/A, not applicable; PCS, posterior circulation stroke.
