Association between door-to-needle time and outcomes in acute ischemic stroke patients treated with intravenous thrombolysis plus mechanical thrombectomy: Analysis from the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS).
Article in European stroke journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionWe aim to evaluate the association between door-to-needle time (DTN) and outcomes in a population of acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT) + mechanical thrombectomy (MT) in the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS). MATERIALS AND
methodsPatients with AIS secondary to middle cerebral artery or intracranial internal carotid artery occlusion with known times of symptoms onset, directly presenting to an MT-capable center, were included in the analysis. According to pre-defined DTN cut-off values (⩽30, ⩽45, and ⩽60 min), we evaluated the association between DTN and outcomes by multivariate logistic regression analyses. Effectiveness outcomes were 3-month functional independence, 3-month excellent outcome and successful reperfusion. Safety outcomes were any intracranial hemorrhage (ICH), symptomatic intracerebral hemorrhage (sICH), and 3-month mortality.
resultsAbout 1602 patients were included in our analysis. After logistic regression analysis, a DTN ⩽ 60 min was significantly associated with 3-month functional independence (OR 1.36; 95% CI 1.02-1.82). DTNs ⩽ 30, ⩽45, and ⩽60 min were significantly associated with successful reperfusion (OR 2.66; 95% CI 1.6-4.43; OR 1.68; 95%CI 1.25-2.26; OR 1.57; 95% CI 1.21-2.05; respectively). A DTN ⩽ 60 min was also significantly associated with lower rate of any ICH (OR 0.61; 95% CI 0.43-0.86). DTNs ⩽ 30, ⩽45, and ⩽60 min were significantly associated with lower 3-month mortality (OR 0.24; 95% CI 0.08-0.67; OR 0.45; 95% CI 0.29-0.72; OR 0.58; 95% CI 0.39-0.84; respectively).
conclusionsIn patients with AIS treated with IVT + MT, a shorter DTN is associated with better outcomes if IVT is initiated within 1 h of hospital admission.
