Odds ratios (OR) and 95% confidence intervals (CI) for level of assistance by different variables in the cumulative logistic regression model

Comparison	OR	95% CI	P
Lumbar plexus vs. epidural	1.39	0.40, 4.82	0.605
POD 0 vs. POD 1	6.24	2.51, 15.5	<0.001
POD 0 vs. POD 2	28.9	8.19, 102	<0.001
POD 1 vs. POD 2	4.63	4.63, 12.8	0.004
10-year increase in age	2.97	1.70, 5.21	<0.001

ORs represent odds of having a lower FIM scale number [16](i.e. needing more assistance) for the relationship described

Significant P values (less than or equal to 0.05) were bolded
