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
The 14-3-3 proteins interact with a wide variety of cellular proteins for many diverse functions in biological processes. In this study, a yeast two-hybrid assay revealed that two 14-3-3ε isoforms (14-3-3ES and 14-3-3EL) interacted with Rab11 in the white shrimp Litopenaeus vannamei (LvRab11). The interaction of 14-3-3ε and LvRab11 was confirmed by a GST pull-down assay. The LvRab11 open reading frame was 645 bp long, encoding a protein of 214 amino acids. Possible complexes of 14-3-3ε isoforms and LvRab11 were elucidated by in silico analysis, in which LvRab11 showed a better binding energy score with 14-3-3EL than with 14-3-3ES. In shrimp challenged with the white spot syndrome virus (WSSV), the mRNA expression levels of LvRab11 and 14-3-3ε were significantly upregulated at 48 h after challenge. To determine whether LvRab11 and binding between 14-3-3ε and LvRab11 are active against WSSV infection, an in vivo neutralization assay and RNA interference were performed. The results of in vivo neutralization showed that LvRab11 and complexes of 14-3-3ε/LvRab11 delayed mortality in shrimp challenged with WSSV. Interestingly, in the RNAi experiments, the silencing effect of LvRab11 in WSSV-infected shrimp resulted in decreased ie-1 mRNA expression and WSSV copy number. Whereas suppression of complex 14-3-3ε/LvRab11 increased WSSV replication. This study has suggested two functions of LvRab11 in shrimp innate immunity; (1) at the early stage of WSSV infection, LvRab11 might play an important role in WSSV infection processes and (2) at the late stage of infection, the 14-3-3ε/LvRab11 interaction acquires functions that are involved in immune response against WSSV invasion.
