Table 2. Comparisons in adjusted hazard ratios of selected split variables between sibling nodes.
| Node | Characteristics | Comparison i, Metformin use in females aged ≤74 years |
Comparison ii, Chronic kidney disease in males aged ≤58 years |
Comparison iii, Smoking in males aged 62–74 years |
Comparison iv, Male sex in those aged >74 years |

Note 1: comparisons were made with adjustment of age and duration of diabetes. Note 2: adjusted hazard ratios (aHRs) are presented in 95% confidence interval (CI). Note 3: statistical significance was set at an alpha level of 0.05.
