Trade-Off Between Early Reperfusion and First-Pass Effect With Tenecteplase Versus Alteplase Before Stroke Thrombectomy.
Article in Journal of the American Heart Association, 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
backgroundEarly reperfusion and first-pass effect are key procedural end points in large-vessel occlusion stroke thrombectomy. Because of greater fibrin specificity, tenecteplase may achieve higher early reperfusion rates compared with alteplase, yet impact of thrombolytic agents on first-pass effect remains unclear.
methodsConsecutive patients with anterior circulation large-vessel occlusion stroke receiving intravenous thrombolysis before endovascular treatment at 2 US stroke centers were reviewed. Early reperfusion was defined as extended Thrombolysis in Cerebral Infarction ≥2b50 on initial angiography. First-pass effect was defined as extended Thrombolysis in Cerebral Infarction 2c-3 after a single pass. Multivariable logistic regression identified predictors of early reperfusion and first-pass effect. Ordinal logistic regression assessed associations of thrombolytic agent, early reperfusion, and first-pass effect with 90-day modified Rankin Scale shift.
resultsAmong 299 patients (tenecteplase 201, alteplase 98), early reperfusion occurred in 60 (20.1%) and was more frequent with tenecteplase compared with alteplase (24.4% versus 11.2%; adjusted odds ratio [OR], 2.31 [95% CI, 1.07-4.98]). Patients without early reperfusion were evaluated for first-pass effect. Of 237 patients, first-pass effect was less frequent with tenecteplase compared with alteplase (30.3% versus 40.2%; adjusted OR, 0.42 [95% CI, 0.23-0.79]). Early reperfusion and first-pass effect each independently predicted better functional outcome, but functional outcomes were similar between tenecteplase and alteplase overall.
conclusionsWe observed higher early reperfusion rates with tenecteplase, but greater first-pass effect with alteplase, while functional outcomes were comparable. This may suggest that the early reperfusion advantage of tenecteplase could be offset by downstream procedural variables such as first-pass effect, highlighting the importance of jointly evaluating both reperfusion and procedural efficiency when comparing thrombolytic strategies.
