CI confidence interval, ICC intraclass correlation coefficientl, OR odds ratio
aUnorthodox view of practice defined as viewing vertebral subluxation as an encumbrance to the expression of health that is corrected to benefit patient well-being; all other views of practice considered orthodox
bRefers to diagnosis that used the term “subluxation”; model adjusted for age, sex, new patient encounter, extended health insurance as payment, injury related to motor vehicle collision, injury related to workers’ compensation, and imaging ordered during encounter
cRefers to duration of patient encounter in minutes (229 encounters excluded due to missing or nonsensical data); based on linear (log-transformed) regression models adjusted for age, sex, new patient encounter, extended health insurance as payment method, injury related to motor vehicle collision, injury related to workers’ compensation, and imaging ordered during encounter
dRefers to treatment that consisted of manual adjustments or treatment using a chiropractic system only; model adjusted for age, sex, new patient encounter, and extended health insurance as payment method (other variables could not be included because model would not converge)
eRefers to reason for encounter for a non-musculoskeletal condition; model adjusted for age, sex, new patient encounter, and extended health insurance as payment method (other variables could not be included because model would not converge)
