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
Adenosine deaminases that act on RNA (ADARs) are RNA editing enzymes capable of converting adenosine into inosine at specific sites within double-stranded RNA (dsRNA), widely distributed across various animal species. Dicer (Dcr), a member of the RNase III family and a crucial component of the RNA-induced silencing complex (RISC), allows ADAR to participate in innate immunity through Dcr-2 in Drosophila. Bombyx mori nucleopolyhedrovirus (BmNPV) is one of the viruses that can cause substantial economic losses to the sericulture industry upon infecting silkworm. Knocking down the expression of BmDcr-2 in silkworm enhances the proliferation of BmNPV. Our previous research revealed the existence of a predominantly expressed subtype, ADARa, in silkworm (BmADARa), which shares homology with Drosophila ADAR. It remains unclear whether BmADARa can also participate in innate immunity through BmDcr-2. Initially, through bacterial challenge experiments, we found that BmADARa exhibited the highest responsiveness to BmNPV stimulation. Further studies demonstrated that BmADARa, in conjunction with BmDcr-2-DEXHc (DEAD-box helicase domain), collectively inhibits the proliferation of BmNPV. BmADARa interacts with the DEXHc domain of BmDcr-2 through its dsRNA binding domain 2 (dsRBD2), thereby enhancing its ability to inhibit BmNPV proliferation. These results lay a foundation for the study of the function and molecular mechanism of BmADARa in innate immunity, and provide a new experimental ideas for antiviral research in B. mori.
