The effect of intravenous thrombolysis on patients with successful thrombectomy depends on final reperfusion grade: A retrospective study.
Article in CNS neuroscience & therapeutics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
aimsAlthough intravenous thrombolysis (IVT) has not shown confirmative effects on the outcomes of patients receiving successful thrombectomy, it might influence the outcomes of a subset of these patients. This study aims to evaluate whether the effects of IVT depend on final reperfusion grade in patients with successful thrombectomy.
methodsThis is a single-center, retrospective analysis of patients with an acute anterior circulation large-vessel occlusion and a successful thrombectomy between January 2020 and June 2022. Final reperfusion grade was evaluated by the modified Thrombolysis in Cerebral Infarction (mTICI) score, which was dichotomized into incomplete (mTICI 2b) and complete (mTICI 3) reperfusion. The primary outcome was functional independence (90-day modified Rankin Scale score 0-2). Safety outcomes were 24-h symptomatic intracranial hemorrhage and 90-day all-cause mortality. Multivariable logistic regression analyses were used to assess the interactions between IVT treatment and final reperfusion grade on outcomes.
resultsWhen comparing all 167 patients enrolled in the study, IVT did not influence the extent of functional independence (adjusted OR: 1.38; 95% CI: 0.65-2.95; p = 0.397). The effect of IVT on functional independence depended on final reperfusion grade (p = 0.016). IVT benefited patients with incomplete reperfusion (adjusted OR: 3.70; 95% CI 1.21-11.30; p = 0.022), but not those with complete reperfusion (adjusted OR: 0.48, 95% CI: 0.14-1.59; p = 0.229). IVT was not associated with 24-h symptomatic intracerebral hemorrhage (p = 0.190) or 90-day all-cause mortality (p = 0.545).
conclusionsThe effect of IVT on functional independence depended on final reperfusion grade in patients with successful thrombectomy. IVT appeared to benefit patients with incomplete reperfusion, but not those with complete reperfusion. Because reperfusion grade cannot be determined prior to endovascular treatment, this study argues against withholding IVT in IVT-eligible patients.
