Table 2 Univariable and multivariable logistic regression analysis for predicting outcomes.
| Variables | Univariable OR (95% CI) | P value | Multivariable OR (95% CI) | P value |
|---|---|---|---|---|
| Sex (0 vs 1) | 0.73 (0.50–1.08) | 0.117 | – | – |
| Smoking (0 vs 1) | 1.07 (0.63–1.80) | 0.804 | – | – |
| Age (≤74 vs >74) (years) | 6.58 (4.27–10.1) | <0.001 | 4.55 (2.64–7.85) | <0.001 |
| EDV (>79 vs ≤79) (ml) | 2.20 (1.43–3.38) | <0.001 | 1.43 (0.59–3.49) | 0.434 |
| LAVI (≤51.88 vs >51.88) (ml/m) | 8.38 (5.34–13.1) | <0.001 | 3.05 (1.67–5.54) | <0.001 |
| LVEF (>60 vs ≤60) (%) | 3.42 (2.22–5.26) | <0.001 | 2.24 (1.26–3.97) | 0.006 |
| RAVI (≤41.67 vs >41.67) (ml/m) | 5.62 (3.59–8.79) | <0.001 | 2.95 (1.61–5.41) | <0.001 |
| The odds ratio (OR) and the corresponding 95% confidence interval (CI) are provided for each variable. Abbreviations. EDV for End-Diastolic Volume, LA for Left Atrium, LAVI for Left Atrial Volume Index, LVEF for Left Ventricular Ejection Fraction, LVIDd for Left Ventricular Internal Dimension in Diastole, LVPWd for Left Ventricular Posterior Wall Thickness in Diastole, LVPWs for Left Ventricular Posterior Wall Thickness in Systole, and RAVI for Right Atrial Volume Index. The univariable analysis examines each variable independently, while the multivariable analysis adjusts for the influence of other variables to assess their combined effect on the outcomes. | ||||
