Validating the bland altman method of agreement datingpro com

However, it is not clear from this paper, like many others reported before [ description of what they perceived to be acceptable limits of agreement.Unless this is described before the study is commenced, it becomes very difficult to make sensible conclusions from the data.The bias therefore allows an estimate to be made of the accuracy of the new device, and the limits of agreement allow an estimate of the precision or random error around the bias.An ideal result therefore would have a very small bias with tight limits of agreement.

There is no real consensus, however, in how these statistical terms relate to any given variable and this has led to much confusion in how to interpret studies and therefore in whether (or not) to accept new measuring or monitoring devices into routine clinical practice.If you have duplicate or multiple measurements per subject for each method, see Bland-Altman plot with multiple measurements per subject.Bland-Altman analysis is used for assessing agreement between two measurements of the same clinical variable.How can we use these concepts when looking at the Bland-Altman plot?First of all, we have to imagine that our reference technique is very reliable.
