1 · What the graph read from it

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.

2 · The registry

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

Subunit vaccines, employing purified protein antigens rather than intact pathogens, require the addition of adjuvants for enhanced immunogenicity with a correct balance between strong activation of the immune system and low toxicity. Here we show that the endogenous (i.e., autologous) non-toxic TLR4 agonist extra domain A type III repeat of fibronectin (FNIII EDA) can synergize with the exogenous (i.e., bacterial), toxic-at-high-dose, TLR9 agonist CpG to induce efficient cellular immune responses while keeping the dose of CpG low. The efficacy of the combined TLR agonists, even at half-doses, led to stronger dendritic cell activation, enhanced cytotoxic T lymphocyte activation as well as stronger humoral response, compared to the individual agonists given at full doses. Immune cells induced after vaccination with the co-adjuvanted formulation could mediate tumor regression in an E.G7-OVA tumor model, and eradicate circulating hepatitis B virus (HBV) in a transgenic HBV model. Together, these results show that endogenous TLR agonists, such as variants of FNIII EDA, can synergize with exogenous TLR ligands, such as CpG, and strongly enhance cellular immune responses, while improving their safety profile.
