The Log of serum GFAP (a), NFL (b), NSE (c), S100B (d), total-tau (e) and UCH-L1 (f) concentration by Marshall CT score.Violin plots and boxplots provide median, range and 25-75th percentile of the log10 biomarker concentration per Marshall CT score grouping I (n=1154), II (n=1120), II-IV (n=120) and V-VI (n=475). P values determined by the Dunn Kruskal-Wallis test with Benjamini-Hochberg correction for multiple comparisons was used for group wise comparison across different CT findings. Significance levels are displayed for statistically significant group wise comparisons, * = p< 0·05, ** = p< 0·01, *** = p< 0·001. Red dotted line indicates the median of Marshall Score I group.
