Comparison of time in days from first joint swelling to fulfillment of the 1987 or 2010 American College of Rheumatology/European League Against Rheumatism criteria and to first treatments between male and female patients with incident rheumatoid arthritis between 2009–2014.^*

^*Values in table are time in days from first documented joint swelling to each outcome, reported as median (25^th percentile, 75^th percentile)

^**Diagnosis of RA or inflammatory arthritis was made in all but 5 patients (all female). All patients met both 1987 and 2010 criteria for RA.
