High-throughput screening for identification of influenza a inhibitors using a cell-based immunofluorescence assay.
Article in Antiviral research, 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
A highly sensitive cell-based imaging assay has been used to screen a 200,000 compounds library for potential influenza antivirals. Compounds were screened at a concentration of 10 μM against the influenza strain A/Udorn/72 (H3N2) and the duplex capability of the assay was taken advantage of to select compounds with no or low cytotoxicity. The assay was also used for confirmation in concentration-response of the active compounds. In the set of confirmed hits, three major structural clusters, 23 minor clusters and 86 singletons were identified. Further evaluation of anti-influenza activity was performed for two additional influenza strains of the H1N1 subtype, A/WSN/33 and A/California/07/09. Three compounds from cluster A, SRI-44211, SRI-44215 and SRI-44221 showed selectivity indices for the pandemic strain A/California/07/09 in the range of 54.3-252, providing evidence that the core structure of cluster A could play a relevant role in their inhibitory potency and may serve as a starting point for future hit-to-lead optimization efforts.
