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
Influenza a virus exploits host machinery to benefit its replication in host cells. Knowledge of host factors reveals the complicated interaction and provides potential targets for antiviral treatment. Here, instead of the traditional proteomic analysis, we employed a 4D label free proteomic method to identify cellular factors in A549 cells treated with avian H9N2 virus. We observed that 425 proteins were upregulated and 502 proteins were downregulated. Western blotting and quantitative real-time PCR results showed that the zinc-finger CCHC-type containing protein 3 (ZCCHC3) levels were markedly induced by H9N2 infection. Transient expression assay showed that ZCCHC3 expression decreased NP protein levels and viral titers, whereas knockdown of ZCCHC3 enhanced viral growth. Specifically, ZCCHC3 promoted the expression of IFN-β, leading to the increased transcription of IFN downstream antiviral factors. Surprisingly, viral NS1 protein was able to antagonize the antiviral effect of ZCCHC3 by downregulating IFN-β. Eventually, we observed that chicken finger CCCH-type containing protein 3, named ZC3H3, could also suppress the replication of H9N2 virus and the coronavirus-infectious bronchitis virus (IBV) in DF-1 cells. Together, our results showed the cellular proteomic response to H9N2 infection and identified ZCCHC3 as a novel antiviral factor against H9N2 infection, contributing to the understanding of host-virus interaction.
