Network meta-analysis of the efficacy of nine drugs for cognitive function in patients with Alzheimer's disease.
Review in Journal of Alzheimer's disease reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Alzheimer's disease (AD) remains a global challenge, and the comparative cognitive efficacy of emerging pharmacotherapies is still unclear. Objective: To compare and rank nine pharmacological agents against placebo in AD with respect to key cognitive outcomes using a network meta-analysis. Methods: We systematically searched randomized controlled trials published up to May 2025 that evaluated aducanumab, lecanemab, donanemab, gosuranemab, semorinemab, tilavonemab, zagotenemab, masupirdine, or sodium oligomannate in AD. The primary outcomes were Clinical Dementia Rating-Sum of Boxes (CDR-SB) and Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog); Mini-Mental State Examination (MMSE) was a secondary outcome. Treatments were ranked using the Surface Under the Cumulative Ranking curve (SUCRA). Results: Fifteen randomized trials encompassing 33 treatment arms were included. No drug demonstrated statistically robust superiority over placebo in primary outcomes. Semorinemab and tilavonemab achieved highest SUCRA rankings, but without significant pairwise advantage. For MMSE, aducanumab showed a modest mean difference versus placebo (1.98, 95% CI 0.03-3.93), though evidence of publication bias reduced confidence. Conclusions: Current pharmacological treatments do not consistently outperform placebo in AD. Tau-targeted antibodies (semorinemab, tilavonemab) display modest but non-significant promise, whereas aducanumab's apparent benefit is likely confounded by publication bias. Further large, rigorous randomized controlled trials and improved preclinical models are essential.
