Gene symbols and definitions: CCL5, C‐C motif chemokine ligand 5; CSF2, colony‐stimulating factor 2; CSF3, colony‐stimulating factor 3; CXCL1, C‐X‐C motif chemokine ligand 1; CXCL3, C‐X‐C motif chemokine ligand 3; CXCL5, C‐X‐C motif chemokine ligand 5; CXCL10, C‐X‐C motif chemokine ligand 10; IL1α, interleukin‐1alpha; IL1β, interleukin‐1beta; IL8, interleukin 8; TNF, tumour necrosis factor.

*Significant after Bonferroni correction. If comparisons showed no differences these were omitted from the table.
