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
backgroundForensic DNA typing has become widely accepted in criminal investigations, familial relationship testing, and identification. This process currently relies on the analysis of short tandem repeat (STR) markers. This is because DNA profiling serves as a highly effective means of identifying individuals on the basis of their distinct genetic characteristics. DNA evidence can also be utilized to clear innocent suspects of any wrongdoing. Recent technological advancements in DNA profiling, such as the implementation of statistical methods, have increased the precision of this tool in forensic investigations.
objectiveThe main objective of this study was to evaluate the forensic efficiency parameters of the D13S317 marker in closely related family members in Gondar town, Northwest Ethiopia.
methodsTo conduct this study, 87 blood samples were collected in EDTA tubes from various kebeles in Gondar town between October and December 2024. DNA was extracted via the salting-out method, and PCR amplification was performed with forward and reverse primers. After amplification, the PCR products were analyzed on a 1.8 % agarose gel and visualized with a gel documentation system.
resultsThe discrimination power, random match probability, typical paternity index, polymorphism information content, and genetic diversity of the D13S317 marker were 0.77, 0.232, 0.5, 0.73 and 0.77, respectively. Five alleles were also confirmed, with the 192 bp allele exhibiting the highest frequency at 33 %, whereas the 176 bp allele had the lowest frequency at 5.7 %.
conclusionThe D13S317 marker has average discrimination power, making it a valuable tool for DNA profiling, paternity testing, and population genetics studies.
