Figure 1.

Flowchart of patient enrollment process. Patients were excluded when alternative diagnoses such as microcrystalline arthritis or a defined connective tissue disease became apparent over follow-up. Patients were removed by the team during follow-up, when repeatedly not compliant or too sick (usually from associated comorbidities) to come to their follow-up appointments. A few patients were also removed by the treating rheumatologist when their disease was no longer active and follow-up was not felt to be clinically justified. ‘Visits not done’ refer to missed visits at that specific evaluation, while ‘planned visits’ refer to visits to be done after the report date.
