Following publication of the original article [1], the authors reported an error in selection of periodontitis datasets. The two datasets used for differential gene analysis of periodontitis had overlapping samples. To be strict, they cannot be used as mutual verification. So, the authors clarified the limitations of the overlapping datasets in discussion part. It was added as limitation five: (V) When selecting the dataset of periodontitis, we only focused on the size of the samples, while ignoring the overlap of the samples. Strictly speaking, they cannot be used as mutual verification, and more datasets should be selected for verification in subsequent studies. The original article [1] has been updated.
