This figure is a boxplot depicting the median FIB-4 across the four different stroke mechanisms according to the TOAST classification, namely Cardioembolic stroke, Stroke of Undetermined Etiology, Large Artery Atherosclerosis and Small Vessel Occlusion. Error bars represent the 25th and 75th quartile of FIB-4 for each TOAST mechanism. Mann–Whitney U test determined that there was a significant difference between FIB-4 between Cardioembolic stroke and each of the four TOAST stroke subtypes groups at p < 0.001. The Kruskal–Wallis test, which determined if there was overall a statistically significant difference between any one of the four groups, was also statistically significant at p < 0.001.
