Time of diagnosis	N	Physician‐diagnosed FM Patients Meeting FM Criteria % (95% CI)	Mean PSD Scores in Physician‐Diagnosed FMa
0‐6 mo	12	25.0 (5.5, 57.2)	9.7
6 mo‐ <12 mo	21	14.3 (3.0, 36.3)	9.7
1‐3 y	27	29.6 (13.8, 50.2)	11.4
>3 y	129	38.0 (29.6, 46.9)	13.7
0‐12 mo	33	18.2 (7.0, 35.5)	8.9
All times	189	33.3 (26.7, 40.5)	12.4
