Intra-Arterial thrombolysis after SUCCESSful angiographic recanalization in acute large-vessel occlusion stroke of the anterior circulation (IA-SUCCESS): a multicentre, randomised, clinical trial protocol.
Article in European stroke journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06768138 (Intra-Arterial Thrombolysis After SUCCESSful Angiographic Recanalization in Acute Large Vessel Occlusion Stroke of the Anterior Circulation), which is not on this map.

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.

Abstract
backgroundIntra-arterial thrombolysis (IAT) following successful mechanical thrombectomy (MT) in patients with anterior circulation large-vessel occlusion (LVO) improves cerebral tissue reperfusion and consequently clinical outcome, but has to be validated in non-Asian populations. We hypothesised that IAT with alteplase versus no IAT leads to a better clinical outcome in patients with anterior circulation LVO stroke who have successful angiographic recanalisation. STUDY
designIntra-Arterial thrombolysis after SUCCESSful angiographic recanalization in acute large-vessel occlusion stroke of the anterior circulation (IA-SUCCESS) trial is a phase 3 investigator-initiated, multicentre, randomised, open-label, blinded-endpoint (PROBE) clinical trial with a health economic evaluation conducted in France. Patients with acute ischaemic stroke due to anterior circulation LVO within 24 h of stroke onset and successful angiographic reperfusion (defined as extended Thrombolysis in Cerebral Infarction score 2b-3) after intravenous thrombolysis alone, MT alone or both will be randomised in two balanced parallel groups (1:1) to receive either IAT with alteplase (0.225 mg kg-1 and a maximum of 20 mg) injected in the ipsilateral internal carotid artery or no IAT. A total of 626 patients will be included. STUDY ENDPOINTS: The primary outcome is the functional outcome on the modified Rankin Scale at 90 (±15) days. Standard secondary clinical outcomes are assessed at 24 (±6) h, 5-7 days, 90 (±15) days and 12 (±1) months. Safety outcomes include mortality at 90 (±15) days and intracranial haemorrhage. SUMMARY: The IA-SUCCESS trial will provide high-quality randomised data on the clinical efficacy and safety of intra-arterial alteplase following successful angiographic recanalisation in European patients with ischaemic stroke due to anterior circulation LVO intended for MT.
