In fact, although anti-ENA screen tests, usually containing anti-Jo1 antibodies, are routinely performed on these patients, non-anti-Jo1 ARS are rarely tested. findings were comparable and the onset mainly began with a single triad finding in all groups despite some differences in overall prevalence. The ex-novo occurrence of triad findings was only reduced in the anti-PL12-positive cohort, however, it occurred in a clinically relevant percentage of patients (30%). Moreover, survival was not influenced by the underlying anti-aminoacyl tRNA synthetase antibodies positivity, which confirmed that antisynthetase syndrome is usually a heterogeneous condition and that antibody specificity only partially influences the clinical presentation and evolution of this condition. 0.0125, reported as *** 0.001, ** 0.01).
