Identification of Key Gene Targets for Periodontitis Treatment by Bioinformatics Analysis

Figure 1

Clustering of samples and determination of soft-thresholding power. (a) The clustering was based on the expression data of GSE6751, which contained 59 samples of blood at four time points: 15 samples at 1 week prior to periodontal treatment, 14 samples at treatment initiation, 15 samples at 6 weeks postbaseline, and 15 samples at 10 weeks postbaseline. (b) Analysis of the scale-free fit index for various soft-thresholding powers. (c) Analysis of the mean connectivity for various soft-thresholding powers.
