Dependent variable was acute or persistent PTH, while independent variables were age, sex, history of migraine (MigHis), loss of consciousness during head injury (LOC), previous head injury (PrevHI), medication overuse (MO), pre-existing psychological history (PPH), and new PTH-associated comorbidities (NewCom). Variables in bold font were found to statistically significantly contribute to the prevalence of persistent PTH. Results are displayed using unstandardized and standardized regression coefficients (β), odds ratio (OR), and p-values
