COVID-19 cohort (n = 309) | Pre-COVID-19 cohort (n = 407) | Incidence rate ratio (95%CI) | |
---|---|---|---|
All suspected stroke presentations, n (%) | 309 | 407 | 0.76 (0.65–0.88) |
Ischemic stroke or TIA, n (%)a | 212/309 (69) | 248/407 (61) | 0.85 (0.71–1.02) |

Other, n (%)b | 77/309 (25) | 115/407 (28) | 0.66 (0.50–0.89) |
aNumber of ischemic strokes and TIAs were (COVID-19 vs. pre-COVID-19): ischemic stroke (180 vs. 194), and TIA (32 vs 54)
