Positive for five variables	12.22% (33/270)	0.64% (2/312)	0.46	0.87	0.96	16.50	19.07	0.88
Positive for four variables	13.70% (37/270)	1.60% (5/312)	0.46	0.87	0.88	7.41	8.55	0.88
Positive for three variables	27.04% (73/270)	3.31% (10/302)	0.46	0.87	0.87	7.33	8.44	0.75
Positive for two variables	30.00% (81/270)	6.73% (21/312)	0.46	0.87	0.79	3.86	4.46	0.75
Positive for age ≥ 67	51.11% (138/270)	24.68% (77/312)	0.46	0.87	0.64	1.79	2.07	0.65
Positive for subscapularis tendon tear	54.44% (147/270)	23.72% (74/312)	0.46	0.87	0.68	2.01	2.30	0.60
Positive for degree of Patte ≥2	54.44% (147/270)	13.78% (43/312)	0.46	0.87	0.71	2.71	3.95	0.53
Positive for hs-CRP > 1 mg/L	60.74% (164/270)	23.72% (74/312)	0.46	0.87	0.61	1.50	1.92	0.71
Positive for pain VAS ≥7	59.63% (161/270)	27.24% (85/312)	0.46	0.87	0.65	1.89	2.19	0.55

A total of 582 patients (270 in the biceps tendon tear group and 312 in the biceps tendon intact group) were included in this analysis. The cutoff values of age ≥ 67 years, degree of Patte ≥2, and pain VAS ≥7 were determined using the ROC curve method. The combination of four positive variables did not include the variable of hs-CRP > 1 mg/L. The results of the combinations of triads and of pairs of positive variables were derived from the values of the highest positive likelihood ratios among those triads and pairs
