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
Infectious laryngotracheitis (ILT) remains a significant concern for the poultry industry worldwide due to its impact on animal welfare and its substantial economic consequences. The disease is caused by the alphaherpesvirus, infectious laryngotracheitis virus (ILTV). This study investigated in vitro host-virus interactions of a glycoprotein G (gG) deletion mutant vaccine strain of ILTV (ΔgG ILTV), and its parent wild-type strain (CSW-1 ILTV). Inoculations were performed separately for the two strains of ILTV using both a primary (chicken embryonic kidney, CEK) and a continuous culture (leghorn male hepatoma, LMH) of chicken cells. Transcriptome analysis was performed at 12 hours post infection. Each cell-type displayed distinct effects on host and viral gene transcription, with a greater number of viral and host genes differentially transcribed in CEK cells and LMH cells, respectively. Both cell-types infected with either strain demonstrated enrichment of pathways related to signalling, and gene ontologies (GO) associated with chemotaxis. Infection with either strain upregulated both SOCS proteins and certain proto-oncogenes, which may contribute to prolonged viral persistence by promoting immunosuppression and preventing apoptosis, respectively. Patterns of gene transcription related to cytokines, chemokines, endosomal TLRs, and interferon responses, as well as pathways associated with histone acetylation, transport, and extracellular matrix organization were similar within each cell type, regardless of the viral strain. In CEK cells, GO terms and pathways were downregulated uniquely after CSW-1 ILTV infection, indicating a viral-strain specific effect in this cell-type. Overall, this study highlights that the observed differences in host and ILTV gene transcription in vitro were more strongly influenced by the cell-types used rather than the presence or absence of gG. This underscores the importance of cell-line selection in studying host-virus interactions and interpreting experimental results.
