Efficacy of reduced-size short tandem repeat PCR analysis for degraded DNA samples.
Article in Genes & genomics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundShort tandem repeats (STR) typing is an essential analysis method for human identification in forensic field. When DNAs obtained from the field as evidences are severely degraded or in too small amounts, STR analysis often shows allele drop-out.
objectiveTo improve STR analysis for degraded DNA or trace DNA, reduced-size STR (rSTR) polymerase chain reaction (PCR) system was devised by selecting relatively large-size STR loci.
methodsThe rSTR PCR system consisted of 8 loci (amelogenin, SE33, CSF1PO, D7S820, D13S317, D2S1338, TPOX, and FGA). The size of PCR product was reduced by designing new primers in the flanking region. The efficiency of this system was verified against existing kits through concordance study, sensitivity study, efficiency study, and casework sample study.
resultsThe size of PCR product in the rSTR PCR system was reduced to be less than 322 bp. The amplicon of each locus was reduced by about 100 bp on average. Results of this rSTR PCR system were confirmed using 146 Korean samples and other commercial kits. The rSTR PCR system was capable of analyzing DNA samples with a minimum amount of DNA of 16 pg and a degradation index of 4.215.
conclusionThe rSTR PCR system was more effective than other PCR kits for obtaining genetic profiles from a small amount of DNA or degraded DNA. The combination of this new system and other commercial kits is more effective than existing systems. This combination is expected to be helpful for the identification of unidentified bodies and skeletal samples.
