Fig. 5From: Relative abundance of the Prevotella genus within the human gut microbiota of elderly volunteers determines the inter-individual responses to dietary supplementation with wheat bran arabinoxylan-oligosaccharidesCorrelation of habitual fibre intake and Prevotella proportional abundance from first washout sample (baseline) in the Prevotella-plus group of volunteers (R2 = 0.503, p = 0.07). One volunteer in the Prevotella-plus group (volunteer 8) did not provide a first washout sample and therefore was not included in this figureBack to article page
