Table 1. Cutoff scores used for age- and sex-standardised prevalence rates of fatigue.

Age group	⩽39 years	40–59 years	⩾60 years
Men	⩽8	⩽10	⩽13
Women	⩽10	⩽11	⩽13

Note: Cutoff scores were set such that 75% of the general population in the same age and gender groups would be classified as not fatigued (Schwarz et al, 2003).
