Differences in characteristics between patients with and without tumor measurements by comparator tests were compared with independent samples t-tests for continuous variables and with chi-squared or Fisher's exact tests for categorical variables.
Also the detection of the diagnostic accuracy of index test F-FDG-PET -CT) imaging F-FDG-PET -CT a neuroblastoma tumour and its metastases, and to compare this to comparator test I-MIBG (SPECT-CT) scintigraphy, could not be calculated because oF-FDG-PET -CT available data at time oF-FDG-PET -CT.
Be sure that when the DETR finally does its public-sector comparator tests on the London Underground to see that it represents value for money, the four years of suffering experienced by London travellers will be written out of the script.
"It is really a matter for the OECD exactly which people have been in comparator tests, but the OECD has verified that Shanghai is three years ahead of the UK and Singapore is two years ahead".
It's not clear to me if the comparator test was ever FDA approved, but it appears from my interpretation of the data that it was not.
In the absence of a lengthy FDA approval process, tests can be cleared by FDA and given similar treatment if they are demonstrated to be roughly equivalent to a former comparator test.
In this case I-MIBG would be the comparator test.
Comparator test: I-MIBG scintigraphy, if F-FDG-PET -CT) imaging was the index test.
Forest plots of MRI and comparator tests (absolute mean differences with pathology).
Number of participants, study design, index and comparator test, mean age and gender of selected studies.
Percentage agreement between MRI and pathology was greater than that of comparator tests (six studies).
