Coefficients represent odds ratios; standard errors in squared brackets; Age numerically coded according to seven age groups; Residence equals one for patients living in Munich; Prosthesis equals one for hip replacement; Time period equals one if surgery was 12–17 months ago (compared to < 12 months). \(^{*}{{p}}<0.05; \,^{**}{{p}}<0.01; \,^{\dagger }{{p}}<0.1\)
