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

backgroundAfrican swine fever (ASF) is a viral disease that affects pigs and wild boars providing economic burden in swine industry. METHODS AND

resultsIn this study, we investigated the effect of deleting the ASFV multigene family 110 (MGF110) fragment (1 L-5-6 L) on apoptosis modulation and the expression of proinflammatory cytokines. Gene expression in swine peripheral blood macrophages infected with either the parental "Volgograd/14c" strain or the gene-deleted "Volgograd/D(1L-5-6L) MGF110" strain was analyzed. Caspase-3 activity was 1.15 times higher in macrophages infected with the parental ASFV strain compared to the gene-deleted strain. Gene expression analysis of Caspase-3 (Cas-3), Interferon-A (IFN-A), Tumor Necrosis Factor A (TNF-A), B-cell Lymphoma-2 (Bcl-2), Nuclear Factor Kappa B (NF-kB), Interleukin-12 (IL-12), and Heat Shock Protein-70 (HSP-70) using RT-qPCR at various time points after infection revealed significant differences in expression profiles between the strains. The peak expression of cytokines (except NF-kB) occurred at 24 h post-infection with the "Volgograd/D(1L-5-6L) MGF110" strain. In samples infected with the ASFV "Volgograd/14c" strain, the most intense expression was observed at 72 and 96 h, except for Bcl-2 and NF-kB, which peaked at 6 h post-infection. The cytokine expression trend for the "Volgograd/D(1L-5-6L) MGF110" strain was more stable with higher expression values.

conclusionThe expression trend for the parental strain increased over time, reaching maximum values at 72 and 96 h post-infection, but the overall expression level was lower than that of the gene-deleted strain. These findings suggest that deleting the multigene family 110 members (1 L-5-6 L) contributes to ASFV attenuation without affecting virus replication kinetics.
