To establish reference intervals (RIs) for work ability, at-work productivity loss and overall in the general working population to compare ability of patients with inflammatory rheumatic musculoskeletal disease (iRMD) this population. Cross-sectional analysis among iRMDs controls without having paid participating a Dutch cohort study. They reported on three outcomes: (0-10), (0%-100%). A generalised additive model location, shape scale parameters was used age-specific RIs percentile curves controls. The proportion below each curve compared. 413 were included; 73% female, mean age 53 (SD 10) years, 60% had high education, 8.7 (1.6), 6.3% (7.2) 11% (25.6).Percentile illustrated that at-work/overall worse increasing age. For instance, 95% RI 22 29-year individuals 5.9-10, while between 50 59 it 4.9-9.1. Patients compared outcomes, especially loss. Work are not perfect population, based newly developed outcomes. This calls caution overestimate iRMD impact Nevertheless, have higher loss,
