Clinical symptoms changes in MTBI patients with PTH from acute to subacute phase related to HCs. A Cognitive function (indexed by score of DSC) improvement in patients from acute to subacute phase. The subpanel shows cognitive function change for each patient from acute to subacute phase, which indicates significant cognitive function improvement from acute to subacute phase in patients. B Reduced traumatic-induced headache impact (indexed by score of HIT) in patients from acute to subacute phase. The subpanel shows headache impact change for each patient from acute to subacute phase, which indicates significant reduced headache impact from acute to subacute phase in patients. MTBI, mild traumatic brain injury; PTH, posttraumatic headache; HCs, healthy controls; DSC, Digit Symbol Coding; HIT, the short-form Headache Impact Test. ^**, P < 0.01; ^***, P < 0.001; ns, not significant.
