Linear regression model including a main effect for each primary treatment assignment and a main effect of booster (i.e. No interaction included between primary and booster treatment assignment) adjusting for baseline NDI and NPI, age, sex, duration of neck pain > 5 years, use of medications for NP, and race (White, Non-Hispanic vs other).
