High ApoB (>1) was associated with increased odds of non-severe stroke but not severe stroke for all stroke, with no significant difference in odds of severe stroke compared with non-severe stroke among matched cases (severe stroke OR 0.97; 95% CI 0.90–1.05; non-severe stroke OR 1.11; 95% CI 1.05–1.18; pheterogeneity = 0.006; pcase-case = 0.11) (Table 2). Here, APOB is linked to stroke disorder.
