Immunotherapy with a short-lived anti-PD-L1 antibody in Alzheimer's disease: a phase 1b, randomized, double-blind trial.
Trial report in Nature medicine, 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
While Alzheimer's disease (AD) is initiated by amyloid plaque accumulation, its progression involves local neuroinflammation that the brain cannot resolve when age-related dysfunction of the systemic immune system limits peripheral immune support. Preclinical studies using rodent models showed that transient systemic blockade of programmed death-ligand 1 is associated with reduced neuroinflammation, neuroprotection and attenuation of disease progression. Based on the underlying mechanism, a new short-lived anti-programmed death-ligand 1 antibody with Fc-effector silencing and reduced FcRn binding (IBC-Ab002) was engineered. Here, we report a randomized, double-blind, phase 1b first-in-human trial in early AD, with safety and tolerability as the primary endpoint. Forty participants were enrolled across five ascending dose cohorts (1-30 mg kg
