Spearman’s correlation coefficients (and p-values) between direct measures of occupational physical activity levels and moderate and vigorous activity outside of work in minutes performed in short bouts and self-reported minutes at moderate and vigorous occupational and outside of work physical activity among participants of the (n=55)^†
