We measured cardiac output using 2 methods. We performed Bland Altman test and also calculated the correlation between the two methods.
I have recently come across some articles where for similar studies Morey’s Error Grid Analysis and Polar Plot analysis. Is it mandatory to do these tests? Do they offer any advantage over Bland Altman agreement? How do we perform Morey’s Error Grid Analysis and Polar Plot analysis?
Any help is welcome.
warm regards
