Sensitivity analysis showing the association between varying FMI cutpoints and BCR and class of obesity and BCR
| Multivariable HR (95% CI) | p | |
|---|---|---|
| According to obesity categories (ref = non-obese) | ||
| Class 1 obesity | 0.94 (0.66–1.35) | 0.75 |
| Class 2 obesity | 1.38 (0.83–2.31) | 0.21 |
| Class 3 obesity | 0.66 (0.10–4.80) | 0.68 |
| According to different FMI cutpoints | ||
| FMI >6 kg/m2 (ref ≤6 kg/m2) | 0.93 (0.49–1.78) | 0.82 |
| FMI >12 kg/m2 (ref ≤12 kg/m2) | 1.35 (0.84–2.17) | 0.21 |
| FMI >15 kg/m2 (ref ≤15 kg/m2) | 0.64 (0.09–4.67) | 0.67 |
Class 1 obesity=FMI >9–12 kg/m2, Class 2 obesity=FMI >12–15 kg/m2, Class 3 obesity=FMI >15 kg/m2. CI: confidence interval; FMI: fat mass index; HR: hazard ratio.
