Flow chart for player recruitment. Of the 127 male and female Australian footballers enrolled in the study, 34 cases of diagnosed SRC were made known to the research team. After exclusion of 6 players, 28 cases of SRC were assessed for SCAT and serum biomarker profiles across time (i.e. baseline, 2-, 6- and 13-days post-SRC), and diagnostic accuracy (i.e. AUROC analysis) at each post-SRC timepoint was assessed against matched control footballers (see Table 1) without SRC
