Antibodies against oxidized lipids in the plasma. Titers of plasma IgG reactive against oxidized LDL were significantly higher in patients with intracranial aneurysms but no history of SAH (A), as were also the titers of plasma IgG against malondialdehyde (B). Titers for plasma IgM reactive against oxidized LDL (C) or malondialdehyde (D) did not statistically differ among patients with a history of SAH or no history of SAH, although there was a trend towards similar findings as with IgG titers. Box plots represent the median value (horizontal line) and the 25^th and 75^th percentiles (box edges). Range is given with error bars and the small black box displays mean values.
