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
Background: Adrenomedullin has angiogenic and vasoprotective effects in acute ischemic stroke (AIS). This investigator-initiated trial aimed to evaluate the safety, efficacy, and optimal administration of adrenomedullin in treating AIS. Methods: In this single-center, multi-cohort, double-blinded, randomized, placebo-controlled, Phase II trial, patients with AIS received pulsed adrenomedullin (9 ng/kg/min for 8 h daily over 7 days) or placebo in the first-half cohort, and continuous-pulsed adrenomedullin (9 ng/kg/min for 72 h during the first 3 days and 8 h daily between Day 4-7) or placebo in the second-half cohort. We included male and female patients aged 20-90 years with newly confirmed ischemic lesions on diffusion-weighted magnetic resonance imaging, and for whom protocol treatment could be initiated within 24 h of symptom onset. The primary safety endpoint was the occurrence of intervention-related severe adverse events. For the primary efficacy endpoint, the least square means and 95% confidence intervals of National Institutes of Health Stroke Scale (NIHSS) scores up to 7 days post-intervention initiation were calculated using generalized estimating equation models. This trial was registered at Japan Registry of Clinical Trials, jRCT2051190092. Findings: Between January 16, 2020, and November 14, 2021, 60 patients were enrolled (median [interquartile range] age, 75 [66-81] years; NIHSS score, 3 [2-4]; 21 [35.0%] females). Neither intervention-related serious adverse events nor severe adverse events were observed in patients receiving adrenomedullin. No life-threatening adverse events or deaths were reported. The least square means (95% confidence intervals) of the changes in NIHSS scores from pre-treatment to Day 7 were -0.76 (-1.43 to -0.09) in the adrenomedullin group (-1.08 [-2.17 to 0.00] in the pulsed adrenomedullin group and -0.42 [-1.12 to 0.29] in the continuous-pulsed adrenomedullin group) and -1.08 (-2.11 to -0.05) in the placebo group. Interpretation: Adrenomedullin was well tolerated in patients with non-severe, non-embolic AIS, although its beneficial effects were not demonstrated. It is necessary to show the efficacy of adrenomedullin in further clinical trials. Funding: Japan Agency for Medical Research and Development.
