Geometric parameter levels	Deltoid load (% BW)			Joint load (% BW)			Joint load angle (°)
	Humeral lateralization	Polyethylene cup thickness	Glenosphere lateralization	Humeral lateralization	Polyethylene cup thickness	Glenosphere lateralization	Humeral lateralization
	Main effects
	p = 0.004	p = 0.012	p = 0.002	p = 0.275	p = 0.007	p < 0.001	p < 0.001
	Pairwise comparisons
1st configuration level	68 ± 8*	65 ± 9*	61 ± 7*,†	62 ± 8	60 ± 9*	53 ± 7*,†	37 ± 12*,†
2nd configuration level	66 ± 8	67 ± 8†	67 ± 7*	62 ± 8	61 ± 8†	62 ± 7*,‡	35 ± 11*,‡
3rd configuration level	65 ± 8*	68 ± 8*,†	70 ± 11†	61 ± 7	64 ± 8*,†	70 ± 11†,‡	31 ± 11†,‡

1^st, 2^nd, and 3^rd configuration levels correspond to 0, 5, and 10 mm configuration levels for subsequent columns labeled Humeral lateralization and Glenosphere lateralization, and to 3, 6, and 9 mm for columns labeled Polyethylene cup thickness; *,†, ‡ signify significant comparisons between the indicated implant parameter levels (eg, 0 mm and 5 mm) with p < 0.05.
