Plasma inflammatory biomarker profiles across the Alzheimer's disease spectrum in the Bio-Hermes cohort.

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
introductionInflammation contributes to Alzheimer's disease (AD), but its stage-specific and amyloid-dependent patterns remain unclear.
methodsWe analyzed 964 participants from the Bio-Hermes cohort (cognitively normal [CN] = 404, mild cognitive impairment [MCI] = 302, mild AD = 258). Plasma levels of 32 cytokines, neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) were quantified alongside core AD biomarkers. Associations with cognition, amyloid, apolipoprotein E (APOE) ε4, and clinical outcomes were assessed using analysis of covariance, partial correlations, and regression models.
resultsTwenty-four cytokines, NfL, and GFAP differed across cognitive groups. Amyloid stratification revealed a core amyloid-independent profile (14 cytokines + NfL) and a broader amyloid-specific profile including GFAP, interleukin (IL)-1β, and IL-18, implicating microglial inflammasome and astrocytic activation. Stage-dependent patterns suggested inflammation may act as early driver, concurrent process, or late amplifier. Paradoxical associations (e.g., eotaxin-2, IL-2R with better memory) and APOE ε4-linked immune differences indicated context-dependent roles. DISCUSSION: This exploratory study reveals biologically plausible, inflammatory heterogeneity in AD and highlights plasma cytokine profiles as candidate biomarkers and therapeutic targets, warranting investigation.
