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

The antiviral, virucidal, and antioxidant activities of extracts from three plants of the Brazilian Pampa biome (Mimosa bimucronata, Luehea divaricata, and Schinus terebinthifolia), as well as the antiviral and virucidal effects of their major flavonoids, were investigated against Bovine Herpesvirus type 1 (BoHV-1) and Bovine Viral Diarrhea Virus (BVDV). Hydroalcoholic and ethanolic extracts displayed pronounced virucidal activity, with five of six extracts inhibiting viral infectivity in vitro. LC-MS analysis identified 17 phenolic compounds, including quercetin, kaempferol, and tiliroside, which exhibited distinct antiviral profiles. Quercetin exhibited virucidal and antiviral activity against BVDV and markedly reduced the BoHV-1 titer. Kaempferol demonstrated significant antiviral effects against both viruses, whereas tiliroside exhibited virucidal activity against BVDV. Gene expression analysis indicated that these flavonoids altered the transcriptional levels of interferon-related genes, including IFNα, IFNβ, and ISG15, in infected and non-infected MDBK cells. Molecular docking simulations revealed favorable binding affinities (≤ - 7 kcal/mol) between the flavonoids and viral proteins, suggesting potential molecular targets. In addition, all extracts exhibited antioxidant activity, reducing lipid peroxidation and scavenging free radicals. Collectively, these findings highlight plants from the Brazilian Pampa biome as promising sources of antiviral and antioxidant compounds against bovine viral pathogens.
