Preclinical Evaluation of the Efficacy of α-Difluoromethylornithine and Sulindac Against SARS-CoV-2 Infection.
Article in Viruses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Despite numerous research efforts and several effective vaccines and therapies developed against coronavirus disease 2019 (COVID-19), drug repurposing remains an attractive alternative approach for treatment of SARS-CoV-2 variants and other viral infections that may emerge in the future. Cellular polyamines support viral propagation and tumor growth. Here we tested the antiviral activity of two polyamine metabolism-targeting drugs, an irreversible inhibitor of polyamine biosynthesis, α-difluoromethylornithine (DFMO), and a non-steroidal anti-inflammatory drug (NSAID), Sulindac, which have been previously evaluated for colon cancer chemoprevention. The drugs were tested as single agents and in combination in the human Calu-3 lung adenocarcinoma and Caco-2 colon adenocarcinoma cell lines and the
