Identification of Mannose-Capped-Arabinomannan 101-mer as a Potential Influenza Virus Vaccine Adjuvant.

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
Many natural bacterial components as adjuvants can activate the host immune system, but the excessive toxicity and structure-identification challenge limit their applications and structure-activity relationship studies. Herein, we report the role of a series of chemically synthesized mannose-capped arabinomannan motifs from Mycobacterium tuberculosis cell wall, including 18-mer, 19-mer, 27-mer, and 101-mer in regulating host immunity. As an influenza vaccine adjuvant, 101-mer induced significantly enhanced anti-influenza antibody response and immune protection compared with other arabinomannan motifs. 101-mer elicited robust immunoenhancement while exhibiting a favorable tolerability profile, as it did not trigger any observable physiological toxicity or inflammatory reactions in various organs. Mechanistically, we found 101-mer may serve as a Dectin-2 agonist to activate host immunity through Syk/NF-κB signaling. This study provided a new oligosaccharide candidate that can satisfy the required "efficacy-safety" balance for clinical adjuvant development.
