Comparison of SCFA's for the Autism-Probiotic group, the Autism-No-Probiotic group, and the controls. Note that the Valerate data is magnified 10x so that it is visible on the chart. The stars indicate the degree of significance of the result of a t-test comparison of the level of SCFA's in the autism subgroup (Probiotic or No-Probiotic) vs. the controls - * p < 0.05, ** p < 0.01, *** p < 0.001.
