Association of CRP levels and clinical and radiological outcomes in patients with large-vessel occlusion stroke: A MR CLEAN Registry study.
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
introductionInflammation is important in the pathogenesis of acute ischemic stroke (AIS). The association between CRP and outcomes in patients with large vessel occlusion (LVO) stroke receiving endovascular therapy (EVT) has not been fully elucidated. PATIENTS AND
methodsWe used data from the MR CLEAN Registry (2014-2017), including LVO-AIS patients with intracranial carotid atherosclerotic disease (ICAD), extracranial carotid atherosclerotic disease (ECAD) or atrial fibrillation (AF). The primary outcome was modified Rankin Scale (mRS) score at 90 days. Secondary outcomes included mRS ⩾3 at 90 days, all-cause mortality, successful recanalization, and symptomatic intracranial hemorrhages. CRP was analyzed both dichotomously (>3.0 vs ⩽3.0 mg/L) and continuously, using multivariable regression adjusted for potential confounders.
resultsAmong 865 included patients (ICAD: 286; ECAD: 154; AF: 425), median CRP level was 3.4 mg/L (IQR: 2.0-6.1) and 446 patients had elevated CRP (>3.0 mg/L). AF patients had higher CRP than ICAD and ECAD patients (4.0-3.0-3.2 mg/L, p = 0.002). CRP >3.0 mg/L was not associated with mRS in the full cohort (acOR 0.983, 95% CI (0.767, 1.260)) or in any etiological subgroups (ICAD: acOR = 0.968, 95% CI (0.626, 1.496), ECAD: acOR = 1.114, 95% CI (0.617, 2.012), AF: acOR = 0.937, 95% CI (0.653, 1.344)). There was also no association between CRP and any of the other outcomes. When analyzed as a continuous variable, CRP was also not associated with any other outcomes.
conclusionsWe did not observe an association between CRP levels and clinical and radiological outcomes after LVO stroke.
