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 present study describes the design and development of a high density SNP array for indigenous Indian pigs. Using whole-genome resequencing of eight populations, over 61 million variants were discovered and filtered to produce a final panel of 635,974 high quality bi-allelic SNPs with genome-wide coverage. The technical performance of the customized array was validated by genotyping 96 samples from a diverse set of porcine breeds. The genotyping results identified 553,289 markers as Poly High Resolution, while only 0.819% were Mono High Resolution. Average call rate was 99.636% and 91.121% or 579,504 markers were best and recommended. The array effectively captured population-level diversity and resolved genetic structure among Indian pigs. An in silico evaluation using SNPs of the customized array extracted from whole genome sequences distinguished both indigenous and global pig breeds. The developed customized high density SNP array offers substantial opportunities for advancing pig genomics in India. It provides a powerful platform with improved precision for population genetics and admixture analysis in porcine populations.
