Tshwa
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
They traditionally relied on foraging but were forced to leave their hunting grounds in Hwange National Park during the early 20th century, leading to social marginalization.

Description: Differential abundance (FDR adjusted p_value <0.05) between populations according to DESeq2 analysis. Positive values in the log2FoldChange indicate taxa enriched in the first population of the comparison, and negative values represent taxa enriched in the second one.
