Diagnostic characteristics of the RC tear and FTRC tear model vs. no tear

Characteristic	RC tear group	FTRC tear group
Sensitivity	57%	60%
Specificity	80%	77%
Positive predictive value	78%	74%
Negative predictive value	60%	65%
Diagnostic odds ratio	5.40	5.02

Rotator cuff (RC) tear group model consists of the combination of inferior cortical acromial sclerosis, lateral acromial spur and greater tubercle cysts

Full-thickness rotator cuff (FTRC) tear group model consists of the combination of inferior cortical acromial sclerosis, lateral acromial spur, superior migration, and greater tubercle cysts
