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 aim of this study was to purify the Chinese Sacbrood Virus Beijing Miyun (BJMY-CSBV) from infected Apis cerana larvae, clone structural protein gene VP1 (named BJMY-CSBV-VP1), and investigate its biological information. The result indicated that the capsid of CSBV is of spherical shape. Gene clone experiment showed that the BJMY-CSBV-VP1 gene sequence comprised 945 bp, encoding 315 amino acids with relative molecular weight of 35.59 kDa and isoelectric point 9.38 pI. Phylogenetic analysis of amino acid sequences showed that the BJMY-CSBV-VP1 and LNDD_2015 were grouped together. Protein secondary structure prediction showed that the gene contained two α-helices, thirteen β-folds, six polypeptide binding sites, and no disulfide bridge. Simultaneously, the BJMY-CSBV-VP1 was ligated to the expression vector pET32a(+) and then transformed into the Escherichia coli BL21 (DE3) for prokaryotic expression. The optimal expression experiment revealed that the protein was found in the inclusion body. The recombinant protein was successfully purified by washing buffer combined with supersonic fragmentation. In this study, we obtained the purified BJMY-CSBV particles, cloned BJMY-CSBV-VP1 gene, investigated the detailed information of the gene by analyzing the sequence, and obtained the purified recombinant protein, which could help for further understanding of the function of the structural protein gene VP1.
