Variations in complexity across scales. The fractal dimension which is obtained for a range of scales is depicted per patient. To obtain these dimensions, the AAA method was applied to the full 3-week activity sequence for all patients (with \(n_{min}=1\), \(n_{max}=10\times 60\) and \(s=1.1\)) and the slope of the mean-variance relation was evaluated for various aggregation scales n lying between \(n_{min}\) and \(n_{max}\)
