FIGURE 1.

Each line represents a case. Patients are grouped in asymptomatic (cases 1 to 6) and symptomatic (cases 7 to 36). The x‐axis represents days from stroke onset. Red bars, number of days with symptoms of COVID‐19 (fever or respiratory symptoms). Blue bars, days of orotracheal intubation. Dotted red line, days between stroke onset and end/start of COVID‐19 symptoms (in patients not symptomatic at stroke onset). Black star, polymerase chain reaction (PCR) for SARS‐CoV‐2 by nasopharyngeal swab. Black cross, death of patient. Colored circles represent the likelihood of association: red, COVID‐19 probable principal cause of ischemic stroke (IS); yellow, COVID‐19 contributing factor of IS; green, COVID‐19 unlikely contributor of IS. Abbreviations: CE, cardioembolic; crypto, cryptogenic; LAA, large artery atherosclerosis; SVD, small vessel disease; undet., undetermined
