Fig. 1

Pairwise probabilities of co-detection of bacterial and viral agents. Probabilities indicate the percentage of non-acute baseline (orange shading; n = 210) or acute samples (blue shading; n = 145) positive with each microbe pair. Bar charts on the upper or right hand side indicate number of non-acute baseline or acute samples positive for each microbe, respectively. Dark box outlines indicate microbe pairs detected more frequently than expected by chance, as assessed by χ2- or Fisher’s exact test (see also Table 3)
