From: Distinct metabolic biomarkers to distinguish IgG4-related disease from Sjogren’s syndrome and pancreatic cancer and predict disease prognosis

Fig. 4

The expression level of selected metabolic biomarkers. A Caftaric acid. IgG4-RD (n = 87) vs HC (n = 30). B Maltotetraose. IgG4-RD (n = 87) vs HC (n = 30). Cd-Glutamic acid. IgG4-RP (n = 33) vs PC (n = 33). D 1-Stearoyl-2-arachidonoyl-sn-glycero-3-phosphoserine. IgG4-RP (n = 33) vs PC (n = 33). E Hydroxyproline. IgG4-RSD (n = 31) vs SS (n = 31). The Mann–Whitney test was used for the comparison of the relative abundance between IgG4-RD patients and other groups. *P < 0.05, **P < 0.01, ***P < 0.001, ns represented for not significant. IgG4-RD, immunoglobulin G4-related disease; HC, healthy control; IgG4-RP, IgG4-related pancreatitis; IgG4-RSD, IgG4-related sialadenitis or dacryoadenitis; SS, Sjogren’s syndrome; PC, pancreatic cancer
