Multivariate analysis for achievement of 30% maximum possible improvement

Parameter	30% MPI achieved (n = 33)	30% MPI not achieved (n = 9)	Odds ratio 95% CI	p Value
Preoperative active external rotation	15° (−40° to 45°)	35° (20°–45°)	0.71 (0.38–0.90)	< 0.001
Preoperative SST	2 (0–9)	5 (0–9)	0.56 (0.17–1.04)	0.068
Preoperative VAS	70 (10–100)	50 (15–75)	1.02 (0.95–1.11)	0.611
Tear limited to supraspinatus + infraspinatus	n = 16 (48%)	n = 0 (0%)	∞* (2.01 to ∞)	0.020

MPI = maximum possible improvement; SST = Simple Shoulder Test; *odds ratio is infinite owing to presence of zero value.
