    Sensitivity and specificity

    Hi firstly wow thank you seem to be quite knowledgeable in this area. So I’m specifically looking at patient post relocation of the knee looking for associated fractures. So I’m doing a retrospective study, so my pool of patients will be all those with a confirmed dislocation on initial x-ray...

    Sensitivity and specificity

    Hi ok no problem. At the moment I have no data as this will be empirical research. So my research is on looking for fractures on MRI radiology images. I have test A which is a type of MRI scan that looks at the bones and Test B which is another type of MRI scan looking at fluid i.e blood...

    Sensitivity and specificity

    I therefore want to see the sensitivity and specificity of the A or B against the A and B combined which I’m having to assume is giving me the truth.

    Sensitivity and specificity

    Hi, I see what you mean, so when I say there isn’t a gold standard that’s not strictly true, there is a gold standard but it’s only possible in autopsy so not available to me as part of a dissertation. Previous studies using autopsy’s sugest the specificity and sensitivity of test A+B combined...

    Sensitivity and specificity

    Hi thanks for the reply. Hmm sorry, I'm not sure what you mean by the truth of the test? The A + B tests combined provided the highest level of sensitivity and specificity available and I plan to perform Test A then Test B then Test A + B combined on the same patient.

    Sensitivity and specificity

    Hi I have 2 test's A and B which are performed on patients and are done together to give a high level of sensitivity and specificity. However doing both test A and B is expensive. I want to work out the sensitivity and specificity of A individually and B individually to see if there's a...
