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

Y-STRs are among the most important genetic markers for forensic DNA application and paternal lineage studies. To explore Y-STR diversity in the Sikh population of Sri Ganganagar, Rajasthan, this study involved the random selection of 207 unrelated male individuals. The 27 Y-STRs of the Ingenomics™ Y Profiler™ Plus PCR Amplification Kit were used in this study. Of the 207 male individuals studied, 197 exhibited unique haplotypes. The results revealed the highest gene diversity (0.8907) at the DYS518 locus, whereas the lowest (0.4161) was at the DYS533 locus. Gene diversity (GD), polymorphism information content (PIC), power of discrimination (DC) and matching probability (PM), were found to be highly important for the 27 studied Y-STRs. These parameters underscore the utility of these loci in forensic identification and paternity testing. These findings enhance the Y-STR database for the Sikh population, aiding forensic casework and regional genetic studies.
