  • Biomarkers with median values set in italics had a high number of biomarker values below the detection range.

  • *NR2, NR2Ab and B-FABP showed test results below the detection range. These cases were assigned with a biomarker level fixed at 50% of the lower limit of detection.

  • †Biomarker levels of both groups were compared using Mann-Whitney U tests.

  • NR2Ab, NR2 antibodies; TIA, transient ischaemic attack.
