Article in Forensic sciences research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
This article describes a newly devised autosomal short tandem repeat (STR) multiplex polymerase chain reaction (PCR) system for 19 autosomal loci (D12S391, D13S317, D16S539, D18S51, D19S433, D2S1338, D21S11, D3S1358, D5S818, D6S1043, D7S820, D8S1179, CSF1PO, FGA, TH01, TPOX, vWA, Penta D and Penta E), 27 Y-chromosome STR loci (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS449, DYS456, DYS458, DYS460, DYS481, DYS518, DYS533, DYS570, DYS576, DYS635, DYS627, YGATAH4 and DYF387S1) and amelogenin with six-colour fluorescent labelling. Various parameters were evaluated, such as its accuracy, sensitivity, specificity, stability, ability to analysis of mixtures and effects of changes in the PCR-based procedures. All of the 47 selected STR loci were accurately and robustly amplified from 282 bloodstain samples. The species-specificity was high and some ability to inhibit Hematin was identified. The lowest detectable DNA amount was ≥0.125 ng. All of the male loci of the secondary component were revealed precisely when the control DNA was mixed at male/female and male/male ratios of 1:4 or more. We conclude that the present 19-plex autosomal STR and 27 Y-STR assay is both accurate and sensitive. It constitutes an additional powerful tool for forensic applications.
