CLCP indices (utilization pattern substrate [H′], substrate richness [S], and equitability [E]) of the salivary microbiota of children with celiac disease who were treated with a gluten-free diet for at least 2 years (T-CD children) and healthy children (HC). Data are the means of three independent experiments (n = 3). The center line of each box represents the median, and the top and bottom of the box represent the 75th and 25th percentiles of the data, respectively. The top and bottom of the error bars represent the 5th and 95th percentiles of the data, respectively. The circles in each box plot extend to the outliers of the data.
