Fig. 6From: A microbiome case-control study of recurrent acute otitis media identified potentially protective bacterial generaCorrelations between OTUs. Correlation coefficients between OTUs were calculated by SparCC [58] within the a) Case NPS; b) Control NPS; c) MEF and d) MER. One sample per child was included in each set. Non-significant correlations (one-sided p > 0.05) are coloured white. N refers to the number of samples included in each correlation analysis, which tested for correlations between all OTUs observed in those samplesBack to article page
