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

A novel tuberculosis subunit vaccine specific for Mycobacterium tuberculosis dual antigens, culture filtrate protein-10 (CFP-10) and antigen 85B (Ag85B) conjugated with cholera toxin non-toxic B subunit (CTB), was expressed as a single polypeptide in high amounts and cost-effectively in Escherichia coli. The recovery and purification conditions for the recombinant fusion protein were established. This simple peptide vaccine required no exogenous adjuvant as it contained CTB, a potent immune modulator. The vaccine's physiochemical, structural, and immunological properties were determined using the in-silico tools. It was highly antigenic, non-allergenic, and non-toxic. Its BlastP search with human proteomes excluded the chances of autoimmune reactions. The tertiary structure model (3D) was validated by Ramachandran plot assessment. The 3D structure docking with Toll-like receptors, TLR-1, 2, 4, and 6, showed that the binding affinity between the vaccine peptide and TLRs was high, and their complex was stable, indicating a strong immune response. The in-silico immune simulation revealed the vaccine-induced both innate and adaptive immune responses. In-vivo validation of the immunogenicity of CTB.CFP10.Ag85B in Wistar rats revealed higher activation of IgG immune response compared to either antigen protein. Similar results were also obtained using the C-ImmSim simulation online server. A comparison of immunogenicity of CTB.CFP10.Ag85B with the only available TB vaccine, Bacillus Calmette-Guérin (BCG) or as a booster after vaccination of Wistar rats with BCG, indicated that the IgG levels were the highest in rats vaccinated with BCG, followed by a booster dose of CTB.CFP10.Ag85B fusion protein. The fusion protein would be a safe potential vaccine booster candidate in BCG-primed individuals against TB.
