Microbial community variations in human salivary samples with different body mass index for forensic research: a pilot study
Jiang Huang
Body mass index (BMI) is a crucial phenotypic feature with significant application value in forensic investigations; however, inferring BMI from forensic-related biological samples such as saliva remains challenging. In this study, saliva samples were collected and subjected to 16S rRNA sequencing to characterize microbial community composition, and BMI-associated microbial markers were screened using linear discriminant analysis effect size and the Kruskal–Wallis rank-sum test.
