Proteins differentially detected in systemic sclerosis (SSc). Semiquantitative enrichment of SSc-associated autoantibodies was determined using a binary assessment of autoantibody presence or absence in a sample. Preferential enrichment in SSc was defined as all proteins detected in >50 % of all patient samples at a frequency >1.5-fold relative to controls. a Heat map of proteins differentially detected in SSc. b Network analysis of differentially detected proteins. Community detection was performed using the GIANT global network; functional annotation was performed using gProfiler
