Accurate predictions of postmortem interval using linear regression analyses of gene meter expression data.

Abstract in brief

• The study aims to improve postmortem interval predictions by analyzing gene expression in zebrafish and mice, showing that groups of gene transcripts, rather than individual genes, can accurately estimate the time since death.
• Researchers used linear regression analyses on gene expression data, splitting data into training and testing sets multiple times, and found that specific groups of genes achieved near-perfect prediction accuracy with R values close to 1.
• This approach demonstrates a promising method for forensic investigations, as it provides a precise way to determine postmortem interval based on gene activity, which is more reliable than traditional indicators.]
