After adjustment for covariables being present prior to the ischemic event only MBL levels remained independently associated with lesion size on MRI: The average infarction volume increased by 7.3 ml for every 1000 ng/ml increase in MBL serum levels (standard error 2.32, 95% CI 2.9–12.2, p = 0.002). This evidence concerns the gene MBL2 and infarction.
