Hello all,

I used the program -concord- to generate Bland-Altman plots for a manuscript.
The reviewer is saying that the differences (plotted on the yaxis) are inverted. That is, the title reads Y-X, but it really is X-Y.

My understanding is, and also from manually checking, that if I used the command:
. concord  Y X,  loa(noref)

The y-axis is Y-X   and not X-Y.

I just need a confirmation that I am correct.

Thank you,
Ricardo
