From: The association between medically unexplained physical symptoms and health care use over two years and the influence of depressive and anxiety disorders and personality traits: a longitudinal study

  1. * All RRs were significant with p-values below 0.001. a All analyses were based on measurements at T0 and T2, as depression, anxiety and personality were not measured at T1. Therefore, a new rate ratio was calculated, adjusted for sociodemographic variables and chronic diseases
