As shown in Figures 2A–C, the urine protein levels of LRG1 were higher in patients with AOSD than in patients with RA or neoplasms and HC subjects, and the urine protein levels of ORM1 and ORM2 in AOSD patients were dramatically higher than those in patients with RA, neoplasms, or infections and HC subjects. Here, LRG1 is linked to neoplasm.
