Hello Dr. Indrayan. I don't have an ACADEMIA account, so cannot view that pre-print. But I assume it is the same method that was discussed in this thread: Is that right?

- Clinical agreement between two quantitative measurements on a group of subjects is generally assessed with the help of the Bland-Altman (B-A) limits.

Thank you very much, Bruce, for reminding me about our previous discussions in this group on this method. This now is a much extended and full version of the article that possibly addresses some of the issues raised previously. I should have acknowledged that. It seems my memory is failing me and I take the responsibility.Â

Thanks, John, for your input. I am trying to say that the Bland-Altman method cannot the used to assess agreement unless we know the clinical tolerance limits. These limits can be directly used without using the B-A method. Such a direct method has several positive features that I have tried to enumerate in this article. I hope this addresses your concern.

- I can't remember whether this is something we discussed previously (iif so, my apologies for resurrecting it!) but ....
- .... there would seem to be a conceptual anomaly/inconsistency in the way you present your case in the paper. You start by listing 11 'problems' with the B-A method, and appear to be saying that the 'most severe' of these problems is:
- 10. The most severe problem with this method is the complete dependence of the interpretation of B-A limits on externally determined clinical tolerance limits. .....
- ... but you then go on to describe an approach which uses only the 'clinical tolerance limits'.Â
- I'm not completely sure why such is your view, but if you feel that 'the most severe problem' with the B-A approach is it's reliance on 'clinical tolerance limits', it seems a little odd that you should be proposing an approach which only uses those limits.
- Kindest Regards,
