Aspects of functioning and environmental factors in medical work capacity evaluations of persons with chronic widespread pain and low back pain can be represented by a combination of applicable ICF Core Sets

Table 6 Coverage and efficiency ratios of the different ICF Core Sets for the LBP-reports (n = 45) and the two relevance thresholds

	Number of overlapping categories	Coverage ratio (%)	Efficiency ratio (%)
Relevance threshold ≥ 25% (m = 74)
LBP Brief (k = 35)	27	36	77
LBP Comprehensive (k = 78)	43	58	55
CWP Brief (k = 24)	21	28	88
CWP Comprehensive (k = 67)	41	55	61
Obesity Brief (k = 8)	8	11	100
Obesity Comprehensive (k = 108†)	41	55	38
LBP + CWP + Obesity Brief (k = 45†*)	35	47	78
LBP + CWP + Obesity Comprehensive (k = 143†*)	59	80	41
Relevance threshold ≥ 50% (m = 33)
LBP Brief (k = 35)	21	64	60
LBP Comprehensive (k = 78)	25	76	32
CWP Brief (k = 24)	17	52	71
CWP Comprehensive (k = 67)	26	79	39
Obesity Brief (k = 8)	7	21	88
Obesity Comprehensive (k = 108†)	27	82	25
LBP + CWP + Obesity Brief (k = 45†*)	26	79	58
LBP + CWP + Obesity Comprehensive (k = 143†*)	32	97	22

Note: m = total number of ranked categories above the respective threshold; k = total number of categories in the respective ICF Core Set(s); † = categories aggregated on the second level; * = adjusted for overlap between the categories of the three ICF Core Sets.
