Box plots of the restriction periods using \(T_{{{\text{eff}}}}^{6,24}\), \(T_{{{\text{eff}}}}^{24,48,168}\) and \(T_{{{\text{eff}}, {\text{mod}}}}^{6,24}\) obtained for patients included in the study and assuming that patients lived with a partner < 60 y who was considered as a carer, and worked at a shared office. Symbols show individual patient values and have been randomly displaced in the horizontal direction for improved visibility. Note that in the calculation of hours of travel all results greater than 24 h have been set to 24 h
