1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundRecent clinical trials have shown that patients with large ischemic cores have better outcomes with endovascular thrombectomy (EVT) compared with standard medical treatment (SMT) alone. The authors aim to assess whether the relationship between EVT and improvements in clinical outcomes varies depending on the location of the occlusive sites.

methodsThis study is a subgroup analysis conducted within a prospective, nationwide, multicenter registry. The cohort included patients with acute large vessel occlusion in the anterior circulation and an Alberta Stroke Program Early Computed Tomography Score of 0-5 within 24 h from last known well. The authors utilized the adjusted common odds ratio for a shift toward better outcomes on the modified Rankin Scale after EVT compared with SMT alone as the primary outcome. Safety outcomes included symptomatic intracranial hemorrhage (sICH).

resultsA total of 745 patients with large ischemic cores were included: 272 (36.5%) with internal carotid artery occlusion, 392 (52.6%) with M1 segment of the middle cerebral artery occlusion, and 81 (11.0%) with M2 segment of the middle cerebral artery occlusion. The adjusted common odds ratios were as follows: 1.98 (95% CI: 1.01-3.89) for ICA occlusions, 2.09 (95% CI: 1.35-3.23) for M1 occlusions, and 1.13 (95% CI: 0.43-2.94) for M2 occlusions. There was no significant treatment-by-occlusion site interaction observed ( P =0.69). However, the incidence of sICH was significantly greater in all groups receiving EVT than in those receiving SMT alone. Additionally, the authors observed that the secondary outcomes and subgroup analyses were generally consistent with the main outcomes.

conclusionsIn this study, the authors found that patients with internal carotid artery and M1 occlusion demonstrated a better outcome with EVT, while the benefit for patients with M2 occlusion remains uncertain.
