ACLY and stroke disorder: The frequency of patients with positive aβ2GPI or aCL increased from baseline to 12 weeks (p < 0.001), whereas frequency of positive LA results decreased (p < 0.001).<h4>Conclusions</h4>Positive aβ2GPI and aCL, but not LA, detected either shortly after stroke or after 12 weeks were associated with early-onset CIS.
