Definition of the "rotator cuff (RC) status" composite variable

		Superior-posterior RC status
		Intact	Small or medium tear	Large or massive tear
Subscapularis status	Intact		Group 1	Group 2
	Small or medium tear			Group 3
	Large or massive tear		Group 5	Group 4

Rotator cuff pathology was assessed intraoperatively by the operating surgeon and classified, separately for each of the superior-posterior rotator cuff and the subscapularis, as intact or full-thickness tear (small: 0–1 cm, medium: 1–3 cm, large: 3–5 cm, or massive: >5 cm). CTA patients with RC status 1 (n = 5), GHOA patients with RC status 2–4 (n = 25), and all RC status 5 (n = 2) were excluded from analyses.
