Quantile regression coefficients of physical activity for SIS hand function.
In the subdomain hand function, the coefficient of moderate was 6.7 in quantile 0.1 and 1.2 in quantile 0.7. For high physical activity the coefficient was 3.6 in quantile 0.1 and -0.2 in quantile 0.7. Due to the high number of SIS hand function scores of 100, the maximum score of 100 was reached in quantile 0.7 and the quantile regression coefficients could not be calculated for quantiles 0.8 and 0.9.
Fig 4.
Quantile regression coefficients of physical activity for SIS mobility.
In the subdomain mobility, the coefficient of moderate physical activity was 11.0 in quantile 0.1, while it declined to 1.7 or smaller in all other quantiles. For high physical activity it was 10.4 in quantile 0.1 and declined to 3.2 or smaller in all other quantiles. In the quantiles 0.5 to 0.9 the coefficient was slightly negative. This means, SIS scores turned out to be 11.0 points higher for moderate and 10.4 points higher for patients with high physical activity in the lowest quantile.

Quantile regression coefficients of physical activity for SIS activities of daily living.
In the subdomain activities of daily living, the coefficient of moderate physical activity was 8.0 in quantile 0.1, while it was 2.1 or smaller in all other quantiles. For high physical activity the coefficient was 4.9 in quantile 0.1 and declined to 3.3 or smaller in all other quantiles. In the quantiles 0.6 and 0.7 it was slightly negative.
