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
Herpes simplex virus type 1 (HSV-1) is a major human pathogen with significant morbidity in neonates and immunocompromised individuals. However, antiviral drugs targeting HSV-1 are emerging with antiviral resistance, highlighting the need to identify new targets for future treatment. Once HSV-1 enters the host cells, it recruits host factors to facilitate viral life cycle. In this study, we showed that aryl hydrocarbon receptor (AhR), a ligand-activated nuclear receptor, is required for HSV-1 effective replication and offers an opportunity for pharmacological intervention. Our results showed that HSV-1 infection activates AhR signaling in an interferon-dependent manner. Pharmacological inhibition or knockout of AhR reduced the expression of viral proteins and infectious progeny, while increased AhR signaling promoted the expression of viral proteins and viral replication. Mechanistically, AhR formed a transcription complex with cyclin T1, VP16 and RNA Pol II in the nucleus, bound to viral gene promoters, and promoted their transcription. Additionally, AhR promoted viral replication partially by facilitating the expression of multiple viral receptors. Collectively, AhR is a proviral host factor for HSV-1, and thus may be used as a promising host-directed antiviral target.
