Comparison between the average amount of specific bacteria groups in the different disease states. The averages are calculated based on the height of the probe signals normalized by the signal height of the universal bacterial probe. Further, the averages are normalized to one because of Probe 18-Lactobacillus in particular, which gave much higher signals. There are 34 subjects in the control group, and the CD (Crohn’s Disease) and UC (Ulcerative colitis) group have 30 and 33 subjects, respectively. Standard error of arithmetic mean is shown. The significance of the differences between the averages were tested using a t-test where the statistical significance was accepted at . Only the statistically significant -value is shown in the figure.
