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

Respiratory syncytial virus (RSV) is a major cause of severe respiratory infections worldwide, particularly in infants, young children, and elderly individuals. Despite the availability of preventive options such as vaccines and monoclonal antibodies, effective antiviral therapies for acute infections remain limited. Therefore, we investigated small-molecule entry inhibitors identified in a high-throughput campaing and evaluated the most promising candidates in detail by performing resynthesis and determining their antiviral activity. Unfortunately, analytical investigations by nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography-mass spectrometry (LC-MS) revealed discrepancies between the screening samples and the resynthesized compounds for two compound classes, highlighting the complexity of hit validation and the potential influence of impurities. By publishing these results, we aim not only to underscore the importance of rigorous analytical and biological validation in screening campaigns but also to support the development of improved strategies for identifying reliable RSV inhibitors. We also believe it is important to publish false-positive hits to avoid time efforts on projects that assume such compounds as genuine hits.
