Table 2. Association between FUI and underestimation of mortality in potential survivors (n = 1116).
| Mean FUI (±SD) | Missed events, n | Underestimation of mortality compared to complete follow-up (per cent) | Hazard Ratio (95% CI) | |||
|---|---|---|---|---|---|---|
| Unadjusted | *Adjusted | * Adjusted P Value | ||||
| FUI-quartile 1 (n = 279) | 0.94 ± 0.04 | 8 | 11.1 | 1.00 (reference) | 1.00 (reference) | n/a |
| FUI-quartile 2 (n = 279) | 0.73 ± 0.07 | 31 | 50.4 | 5.44 (2.5; 11.9) | 4.81 (2.2; 10.5) | <0.001 |
| FUI-quartile 3 (n = 279) | 0.39 ± 0.12 | 65 | 59.6 | 11.47 (5.5; 23.9) | 10.0 (4.8; 20.8) | <0.001 |
| FUI-quartile 4 (n = 279) | 0.06 ± 0.05 | 111 | 62.3 | 20.16 (9.8; 41.4) | 18.38 (8.9; 38.0) | <0.001 |
* Hazard ratios (stratified by scenario), confidence intervals and P-values were adjusted for baseline age, sex, time since operation, type of operation (AAA repair vs TAA repair, endovascular repair vs open repair) in a primary adjusted model. In a secondary adjusted model comorbidities (coronary heart disease, diabetes, renal insufficiency, chronic pulmonary lung disease, smoking status, arterial hypertension, dyslipidemia) were considered additionally, but this did not alter the findings of the primary adjusted model
