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
Baculovirus-Bombyx mori protein expression system has mainly been used for translation of eukaryotic proteins. In contrast, information pertaining to bacterial protein expression using this system is not sufficient. Therefore, recombinant nucleases from Serratia liquefaciens (rSlNucAs) were expressed in a Baculovirus-B. mori protein expression system. rSlNucAs containing the native signal peptide (rSlNucA-NSP) or silkworm 30-K signal peptide (rSlNucA-30K) at the NH2-terminus were constructed to enable secretion into the extracellular fraction. Both rSlNucA-30K and rSlNucA-NSP were successfully secreted into hemolymph of B. mori larvae. Affinity-purified rSlNucAs showed high nuclease activity. Optimum pH was 7.5 and half of maximum activity was maintained between pH 7.0 and 9.5. Optimum temperature was 35 °C. rSlNucAs showed sufficient activity in twofold-diluted radioimmunoprecipitation assay buffer and undiluted, mild lysis buffer. Genomic DNA of Escherichia coli was efficiently digested by rSlNucAs in the bacterial lysate. The results in this study suggest that rSlNucAs expressed by the Baculovirus-B. mori protein expression system will be a useful tool in molecular biology. Functional recombinant protein of bacteria was produced by Baculovirus-B. mori protein expression system. This system may be highly suitable for bacterial extracellular protein secreted via Sec pathway.
