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

Background: Tenofovir disoproxil fumarate (TDF) is a first-line nucleotide analog (NA) drug for hepatitis B therapy. Long-term NA therapy increases peripheral T cell levels to enhance antiviral response, while CTLA-4 inhibits the activation. Objective: This study analyzed the interaction between TDF and CTLA-4 through molecular docking. Methods: Target protein and ligand data mining were performed, and proteins were prepared by removing water molecules in the Discovery Studio 2019 software. The energy minimization was performed on ligands using Pyrx v.0.9.8 software. Protein-ligand docking was performed using Autodock Vina integrated with Pyrx v.09.8. Meanwhile, the docking of proteins was accomplished using the Haddock server. The BioVia Discovery Studio 2019 software visualized the interaction between the compound and the docked protein. Molecular dynamics simulations were carried out using the YASARA Dynamic program developed by Biosciences GmbH. Results: TDF ligand has good and stable inhibitory activity against the CTLA-4/B7-1 and CTLA4/B7-2 complexes. TDF docking has been shown to initiate conformational changes, indicating the ligand's inhibitory activity. The significant conformational changes based on superimposition results were shown by the CTLA-4/TDF/B7-2 and CTLA-4/B7-1/TDF complexes. TDF in all ligands undergoes bonding and displacement of binding sites. Conclusion: Treatment with TDF was predicted to have inhibitory activity against CTLA-4, especially in its complex form with B7-1 and B7-2.
