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 limited durability of vaccine protection and the rapid emergence of SARS-CoV-2 variants highlight the need for antiviral strategies that extend beyond vaccination and conventional small-molecule inhibitors. Here, we explored a dual approach combining structure-guided peptides predicted to interfere with the viral replication complex with lethal mutagenesis to limit SARS-CoV-2 replication. Using the crystallographic interfaces of nsp10 with nsp14 and nsp16, we designed short inhibitory peptides predicted to interact with the viral proofreading and RNA-capping machinery. In parallel, the mutagenic analog 5-fluorouracil was evaluated to determine its effect on SARS-CoV-2 in Vero E6 cells. Peptides P1 and P6 exhibited potent antiviral activity with minimal cytotoxicity, whereas 5-FU reduced specific infectivity without impairing genome replication. Combined treatment with 5-FU and peptide P1 resulted in >10
