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
backgroundWorse functional outcome has been reported after hemorrhagic compared to ischemic stroke, yet it remains unclear whether the lesion size, location, or stroke etiology itself results in different degrees of disability. This study compares outcomes in ischemic vs. hemorrhagic stroke patients with matched lesion size and location.
methodsData from the longitudinal cohort study on intracerebral hemorrhage (ICH) care (2006–2015) and a retrospective registry on acute ischemic stroke (AIS) (2011–2015), both conducted at the university hospital Erlangen, were used to investigate patients with a single stroke lesion in the middle cerebral artery territory. Patient characteristics, lesion size and affected brain location according to the Alberta Stroke Program Early CT Score (ASPECTS) regions were balanced using propensity score matching. Functional outcomes (ordinal shift of modified Rankin scale (mRS) at 3 months), 5-year survival (Kaplan–Meier, Cox regression), and burden of disease (Disability-Adjusted Life Years [DALYs] = Years of Life Lost [YLL] + Years Lived with Disability [YLD]) were compared.
resultsAfter propensity score matching, we analyzed 194 patients, divided equally into AIS or ICH cases. We observed a shift in mRS distribution towards better functional outcomes in favor of AIS over ICH (OR: 1.69, 95% CI: 1.02–2.79, p = 0.04), especially in younger patients (age < 75 years, OR: 3.23, 95% CI: 1.58–6.59, p < 0.01) and smaller lesion volumes (< 15 mL, OR: 4.48, 95% CI: 1.85–10.89, p < 0.01). The 5-year survival did not differ between groups (log-rank 0.63). Mean number of DALYs was higher following ICH compared to AIS in general (8.39 ± 5.18 vs. 5.90 ± 4.61, p < 0.001) and per milliliter of parenchymal lesion volume (0.31[0.14–0.81] vs. 0.24[0.10–0.41], p = 0.04). The higher number of DALYs is attributable to the higher number of YLDs (ICH, 3.49 ± 3.3 vs. AIS, 2.31 ± 2.86, p < 0.01) and YLLs (ICH, 4.90 ± 3.27 vs. AIS, 3.59 ± 3.08, p < 0.01) in matched patients following ICH compared to AIS.
conclusionsFor stroke lesions of matched size and location, patients with hemorrhagic stroke had worse functional outcome, greater disease burden in total and per ml, yet comparable long-term survival rates compared to those with ischemic stroke.
