OS rate after surgery among the three groups of patients with ICC without known risk factors. The follow-up group = patients with ICC who were routinely followed-up for DM, HT, and DL (metabolic components); the no follow-up group = those who were not followed-up for metabolic components; the control group = those without metabolic components. Follow-up = patients who received medical treatment or underwent a physical and/or laboratory and/or imaging examination, such as abdominal US, for follow-up of DM, HT, and DL at least every 6 month.
