Table 8.

Concurrent validity: Mean differences between GEDI-SR scale and VSK-SR scale

Age-group	N	Difference Average / Mean difference	SD	95%-Limits of agreement	Concordance correlation coefficient
Age-group	N	Difference Average / Mean difference	SD	95%-Limits of agreement	Pearson's r (95%-CI)
3 years	46	-0.000^a	0.75	-1.47 to 1.47	0.72*** (0.54 to 0.83)
4 years	65	-0.000^a	0.77	-1.52 to 1.52	0,70*** (0.55 to 0.81)
5 years	55	0.000	0.56	-1.11 to 1.11	0,84*** (0.74 to 0.90)
6 years	18	-0.000^a	0.92	-1.8 to 1.8	0.58** (0.17 to 0.82)
overall	184	0.000	0.71	-1.38 to 1.38	0.75*** (0.68 to 0.81)

Note: SD Standard deviation, CI Confidence interval, *** = p < 0.001; ^a values have a slightly negative tendency, which only becomes apparent after the fourth comma position
