| P value | Odds ratio | 95% CI | |
|---|---|---|---|
| Indications for PPV | |||
| VMI | — | ||
| TRD group | 0.003 | 2.941 | 1.433–6.036 |
| Combined TRD and RRD group | 0.042 | 2.637 | 1.037–6.708 |
| VH group | 0.044 | 2.080 | 1.020–4.244 |
| Intravitreal bevacizumab injection | |||
| 2 weeks prior to PPV | 0.003 | 0.167 | 0.050–0.553 |
| At the end of PPV | <0.001 | 0.219 | 0.126–0.382 |
| Combined 2 weeks prior to/at the end of PPV | 0.028 | 0.391 | 0.169–0.902 |
CI = confidence interval; VMI = vitreomacular interface abnormalities; TRD = tractional retinal detachment; RRD = rhegmatogenous retinal detachment; VH = vitreous hemorrhage; SD = standard deviation; PPV = pars plana vitrectomy.
