Influence of treatment on 178 patients with central retinal artery occlusion: results of ordinal logistic regression for visual acuity after treatment
| Effect | No. of Patients | Wald’s χ2 | P | |
|---|---|---|---|---|
| Treatment | Conservative | 116 (65.17%) | ||
| LIF | 62 (34.3%) | 9.38 | b | |

| Gender | Male | 125 (70.2%) | b | |

| Occlusion | Subtotal | 130 (73.0%) | b | |
| Incomplete | 39 (21.9%) | 26.49 | 0.0001 | |
| Complete | 9 (5.1%) | 4.53 | 0.0332 | |
| Age | 18–89 years | 8.71 | 0.0032 | |
| Latency | 1–312 hr | 3.97 | 0.0459 | |
| Initial visual acuity | 0–5 | 43.31 | 0.0001 |
Note.—LIF indicates local intra-arterial fibrinolysis; b, baseline (reference) class; e, removed by backward elimination; (given P values are probability to remove values).
