Thank you for reading the article. The objective of this study was not to show agreement through reporting the Pearson's correlation coefficient. Generally, agreement is not a point when there is a weak correlation, and a strong correlation dies not indicate agreement. Sometimes there is a strong correlation but there is a difference between two devices. The presence of a strong correlation yet a large difference indicates bias, which can be overcome through calibration. ICC is mostly used for repeatability and is less commonly used for agreement. Of course, some studies have used ICC for agreement, which is not correct.
