The p-value of significance test has been given as ‘p < 0.5’ in the Material and methods section (4.4), which is incorrect.
The correct writing for the p-value is ‘p < 0.05’. It should be noted that we correctly wrote the p-value in the electronic supplementary materials and in responding to the reviewers' comments, i.e. ‘p < 0.05’.
All the authors gave their consent to this correction.
