1 · What the graph read from it

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.

2 · The registry

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 ForenSeq™ FGx System (Illumina, San Diego, CA) was initially evaluated in concordance with SWGDAM guidelines for internal validation to determine the quality of the system's components: the ForenSeq™ DNA Signature Prep Kit reagents, the MiSeq FGx™ instrument, and the ForenSeq™ Universal Analysis Software, for the analysis of targeted, forensically informative single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs). This multiplex consisted of STRs (autosomal, X, and Y) and SNPs (identity, ancestry, and phenotypic) that were run using one preparation process. Overall, the ForenSeq™ FGx System performed as well as the traditional capillary electrophoresis-based method in producing usable profile information, along with additional information that could aid in investigative leads. The MiSeq FGx™ System was validated using DNA samples in studies testing reproducibility, repeatability, concordance, sensitivity, and mock case single donor samples. Overall, genotyping results for STRs and SNPs were concordant with the profiles generated from conventional STR analysis using Identifiler and SNPs typed by 23andMe analysis. Genotypes of the ForenSeq™ aSNPs were used to evaluate biogeographical ancestry estimations using ForenSeq™ Universal Analysis Software, FROG-kb database (KIDD aiSNP 55 panel), and 23andMe. The system was shown to provide reproducible genotypes and reliable results were obtained at levels as low as 50 pg. All mock case samples were concordant with the donor profile. The results support consideration of the ForenSeq™ FGx System as an acceptable alternative to current STR and SNP analysis, pending formal developmental and internal validation studies.
