Dunn's multiple comparisons test was used to compare each level of delay between pairs of centres. p Values are shown. Where p>0.05, this was regarded as NS.
* Symptom onset to request to see initial healthcare professional (HCP) of contact (delay 1: patient delay).
† Initial assessment by HCP to referral to a rheumatologist (delay 3: initial HCP delay).
‡ Referral to a rheumatologist to assessment by that rheumatologist (delay 4: rheumatologist delay).
