Reason for ordering the MAP

	Rule-in SLE n (%)	Rule-out SLE n (%)	Differential diagnosis n (%)
Low confidence, n=93	5 (5.4)	51 (54.8)	37 (39.8)
Moderate confidence, n=49	18 (36.7)	14 (28.6)	17 (34.7)
High confidence, n=19	15 (78.9)	0 (0)	4 (21.1)

At T0, the investigators indicated what was the main reason for ordering the MAP and could choose between ruling-in SLE, ruling-out SLE or making a differential diagnosis of connective tissue diseases.

Values represent the number and percentage (%) in each category. Per cent values were calculated based on the total number of patients for whom confidence in SLE diagnosis was low, moderate or high (93, 49 and 19, respectively).
