Associations of ultrasound-based inflammation patterns with peripheral innate lymphoid cell populations, serum cytokines/chemokines, and treatment response to methotrexate in rheumatoid arthritis and spondyloarthritis

Clustering of patients based on serum cytokines/chemokines.
A heatmap representing the serum levels of 20 biomarkers and dendrograms illustrating hierarchical clustering of these cytokines/chemokines and patients (n = 99). The clinical diagnosis (rheumatoid arthritis vs. spondyloarthritis) and the ultrasound-based inflammation pattern (Group 1 vs. Group 2) are provided below the heatmap.
