Following publication of this article, the authors identified some errors in the text and Table 2 that resulted in an incorrect representation of the data and may eventually lead to misinterpretations of parts of the findings of this article.

The respective correction of those issues does not change the main direction or conclusions of the article.

The corrected text, along with the affected rows and columns of Table 2 are highlighted below with bold font and the original article has been updated.

The authors would like to apologize for any inconvenience caused to the readers.

Furthermore, the AUC for differentiating between the TTH- and TTH + groups was 0.69 (OR: 1.61, 95%-CI: 0.73–3.53, p = 0.24).With average T2 as the predictor, the AUC for differentiating between the HC and TTH- groups was 0.68 (OR: 2.03, 95%-CI: 1.01–4.11, p = 0.04), and it was 0.82 for the differentiation between the HC and TTH + groups (OR: 3.80, 95%-CI: 1.36–10.61, p = 0.01). Furthermore, the AUC for differentiating between the TTH- and TTH + groups was 0.69 (OR: 1.61, 95%-CI: 0.73–3.53, p = 0.24).
