  1. *Values are mean (standard deviation) or number (%)
  2. **Baseline characteristics are presented for all participants who had C-reactive protein data at baseline health examination and were included in either the cross-sectional or longitudinal analyses conducted in this study. The mean (SD) of Haemoglobin A1c presented in this table is based on a total of 7,485 participants who had Haemoglobin A1c measurement at baseline. All other baseline characteristics are presented for a total of 14,228 participants who had Haemoglobin A1c measured at a minimum of one health examination
