Data on global positioning system activity space and health outcomes among adult patients with sickle cell disease. A The entire dataset of a representative study participant. Each colour represents a different day. Standard deviation ellipse (SDE) can serve as an indicator for “activity space” and includes at least 68% of the samples by definition. Size of the SDE shown is 238·70 km2 (map has been altered to de-identify the exact home location). B Scatter plot and fitted values for activity space score (log km2) and Center for Epidemiologic Studies Depression Scale (CES-D) depression scores. C Box plot showing distribution of activity space scores (km2) by patients reporting 0/10 pain versus those reporting 1/10 pain or greater. D Scatter plot and fitted values for activity space score (log km2) and haemoglobin levels (g/l). [Colour figure can be viewed at wileyonlinelibrary.com]
