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 sterile alpha motif and HD domain 1 (SAMHD1) protein has been identified as a novel innate immunity restriction factor that participates in processes crucial to the viral life cycle. In the present study, we describe a procedure to generate monoclonal antibodies (MAbs) against porcine SAMHD1 and investigate its characteristics to analyze the expression of endogenous SAMHD1. The open reading frame of porcine SAMHD1 was cloned into the prokaryotic expression vector pCold-TF DNA to construct a recombinant plasmid pcold-pSAMHD1 and induce expression of recombinant porcine SAMHD1 protein by IPTG in Escherichia coli Rosetta. The purified recombinant porcine SAMHD1 protein was used to prepare MAbs of SAMHD1. After subcloning five times hybridoma cell clones expressing SAMHD1, MAbs were generated. Western blot analysis and indirect immunofluorescence assay showed that the overexpressed porcine SAMHD1 in 293T cells and endogenous SAMHD1 protein in porcine cell lines could be specifically recognized by the MAbs produced in this study. In conclusion, specific MAbs of porcine SAMHD1 are reported, and these MAbs provide a valuable tool for further studies of SAMHD1-mediated signaling in virus-infected cells to elucidate the underlying antiviral mechanism.
