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

Although toll like receptor (TLR) ligands are effective vaccine adjuvants, current synthetic TLR2 agonists suffer from low solubility, high cost, and detrimental effect towards protein antigen. Present study aimed to evaluate the immunostimulatory potential of five in-house PAM2CS lipopeptide-based TLR2 agonists (P1, P2, P6, P7 and P8) using peripheral blood mononuclear cells (PBMCs) from chicken (n = 4). Each agonist (10 µg/mL) significantly upregulated the expression of interleukin (IL)-1 β and inducible nitric oxide synthase (iNOS) at 3 h post-treatment with highest expression of IL-1β mRNA was observed with P1. There was a significant up-regulation of interferon (IFN)-β and IFN-γ by treatment with P1 at 3 and 12 h intervals (p < 0.05). Further, IL-4 mRNA was significantly upregulated with P1 and P7 treatment at 12 and 24 h post-treatment respectively. Our results demonstrate that among all five agonists, P1 was the most effective in enhancing immune response genes expression including both type I and type II interferons, and in eliciting a balanced Th1 and Th2 responses.
