Receiver-operating characteristics (ROC) analysis. a) ROC analysis shows good discrimination between Th/To immunoprecipitation (IP)-positive patients (n = 8) and controls (n = 367) including rheumatoid arthritis (RA, n = 141), systemic lupus erythematosus (SLE, n = 67), undifferentiated connective tissue disease (UCTD, n = 17), osteoarthritis (OA, n = 47), ankylosing spondylitis (AS, n = 13), polymyalgia rheumatica (PMR, n = 20), degenerative spine disease (n = 6), fibromyalgia (n = 5), psoriasis arthritis (n = 13), other pathologies (n = 28) and healthy individuals (HI, n = 10). b) ROC analysis shows discrimination between SSc (n = 70) and controls (n = 367). AUC, area under the curve; SSc, systemic sclerosis.
