Study flow chart. Between 1998 and 2007, 5,893 patients were identified with new-onset type 1 diabetes (T1D) in Taiwan. After excluding 301 of those with pre-T1D cataracts and 1,970 of which computed tomography (CT) imaging studies were performed prior to being diagnosed with cataracts, a total of 3,622 cases were included. Equal numbers of age- and gender-matched individuals were selected from the Longitudinal Health Insurance Database (LHID) for analysis.
