IL13 and synovial sarcoma: Specifically, higher levels of C-X-C motif chemokine 11 (OR = 1.24, 95% CI = 1.05–1.48, p = 0.013), C-X-C motif chemokine 6 (CXCL6, OR = 1.51; 95% CI = 1.04–2.18, p = 0.029), and Interleukin-13 (OR = 1.22, 95% CI = 1.02–1.47, p = 0.033) were linked to an increased risk of SS.
