Article in BMJ open, 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
introductionStroke remains a leading cause of disability and mortality worldwide, with an urgent need for novel therapeutic strategies to improve recovery. Bupropion hydrochloride, a norepinephrine-dopamine reuptake inhibitor, may promote motor and cognitive recovery due to its unique mechanism of action. To evaluate the efficacy and safety of early adjunctive treatment with bupropion hydrochloride versus placebo on functional recovery in patients with acute ischaemic stroke. METHODS AND ANALYSIS: BASE is an investigator-initiated, multicentre, randomised, double-blind, placebo-controlled trial. We plan to enrol 1054 eligible patients with acute ischaemic stroke (National Institutes of Health Stroke Scale (NIHSS) score 8-15, within 2-7 days after onset) from approximately 40 stroke centres across China. Participants will be randomly assigned (1:1) to receive either oral bupropion hydrochloride (75 mg two times per day) or matched placebo for 30 days, in addition to standard guideline-based care. The primary efficacy endpoint is the proportion of patients achieving a favourable functional outcome, defined as a modified Rankin Scale (mRS) score of 0-3 at 90 days. Key secondary endpoints include shifts in mRS scores, changes in NIHSS, Hamilton Depression Rating Scale (HAMD-17), Fugl-Meyer Motor Scale scores and quality of life (EQ-5D). Safety endpoints include mortality, vascular events and incidence of adverse events. Analyses will be performed on both the intention-to-treat and per-protocol populations ETHICS AND DISSEMINATION: The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Chongqing Medical University (ID ZZ2025-747-01), and all participants will provide written informed consent. Results will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRY NUMBER: ChiCTR2500105746 (www.chictr.org.cn).
