The association between antiphospholipid antibodies titres and COVID-neurological, hospitalised and non-hospitalised groups

Serum samples were obtained from 106 adult participants. All were divided into the following groups; 29 COVID-non-hospitalised controls, 47 COVID-hospitalised controls, 30 COVID-neurological cases. The antiphospholipid antibody titre levels were measured across the groups for (A) anti-beta-2 glycoprotein-1 [aβ₂GP1] IgG (B) aβ₂GP1 IgM (C) aβ₂GP1 IgA (D) anticardiolipin antibodies [aCL]) IgG, (E) aCL IgM, (F) aCL IgA (G) anti-Antiphosphatidylserine/prothrombin antibodies (aPS/PT) IgG, (H) aPS/PT IgM, (I) anti- domain 1 of β₂GPI (aDIβ₂GPI). The horizontal broken line represents the cut-off for each antiphospholipid antibodies. *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001. P values only shown when groups are significantly different. Missing data Covid-Neuro n = 3, Covid-Hospitalised n = 0, Covid non-hospitalised n = 0.
