The gut microbial abundances of genera enriched in groups do not correlated with BMI, age or gender. The relative abundances of genera overrepresented (above 4) or deficient (below 11) in subjects for each control (n = 41), pHTN (n = 56), and HTN (n = 99) sample are shown. The information for BMI, age and gender of each participant are included in the heat map. (PDF 669 kb)
