Accuracy of different echocardiographic parameters in predicting prognosis
| Echocardiographic parameter | Sensitivity | Specificity | PPV | NPV | Positive likelihood ratio | Negative likelihood ratio |
| RVD | 0.74 (0.6–0.9) | 0.51 (0.4–0.6) | 0.09 (0.06–0.12) | 0.97 (0.94–0.98) | 1.51 | 0.51 |
| RV/LV | 0.44 (0.3–0.5) | 0.64 (0.6–0.7) | 0.08 (0.05–0.12) | 0.64 (0.57–0.71) | 1.22 | 0.88 |
| TAPSE | 0.57 (0.5–0.6) | 0.65 (0.5–0.8) | 0.06 (0.04–0.1) | 0.65 (0.51–0.76) | 1.63 | 0.66 |
Data calculated from studies reporting number of patients with/without study outcome event based on presence/absence of the parameter. PPV: positive predictive value; NPV: negative predictive value; RVD: right ventricular dysfunction as comprehensive definition; RV/LV ratio: right ventricle/left ventricle diameter ratio; TAPSE: tricuspid annular plane systolic excursion.
