In sum, 94\u00b78% of the patients suffered from aspects of metabolic syndrome. Other comorbidities were Crohn's disease (4\u00b75%), ulcerative colitis (4\u00b72%), chronic polyarthritis (5\u00b72%), monoclonal gammopathy or myelodysplastic syndrome (2\u00b75%), leukaemia (1\u00b71%) and lymphoma (0\u00b74%). <jats:styled-content style=\"fixed-case\">DRG<\/jats:styled-content> data do not reflect individual patients, but rather patient cases.
