Time to diagnosis predicts outcome. Linear regression adjusted for sex, age and disease duration. Independent variable: Duration between onset of symptoms and diagnosis. Dependent variable: outcome parameters (BILD, SLAQ, SF-12 mental/physical and SF-36-PFI, FSS). β stand. regression coefficient, HRQoL Health related quality of life. *p < 0.05, **p < 0.01; ***p < 0.001.
