Secondary Care Encounters for OAT vs. SMT as Initial Approach to Long-term Care of cLBP

Propensity Scoring Method	Rate Ratio	CI	SE	P
Binning	2.43	2.40 – 2.46	0.01	<.0001
Weighting	2.67	2.64 – 2.69	0.00	<.0001

Estimate = exponentiated log of rate ratio for Cohort OATC vs. SMTC

SMTC: Initiation of care of cLBP with SMT in 2013 (combination of SMT and SMTX)

OATC: Initiation of care of cLBP with OAT in 2013 combination of OAT and OATX)
