However, many known teratogens cause a number of different types of CA, and heterogeneous clusters with known exposures have been documented [ 35] so the future will lie in more aetiologically relevant classification of CA. Another criterion was the size of the Observed/Expected ratio and associated p value.
The first report demonstrating clinically relevant classification of cancer based on microarray was from Golub et al. [ 4], where a 50-gene signature could distinguish AML (acute myeloid leukemia) and ALL (acute lymphoblastic leukemia) patients with 100% accuracy.
Sagittal magnetic resonance imaging (MRI) sequences are reliable in detection of nerve root contact to intraforaminal disc material, but a clinically relevant classification of degree of contact is lacking.
Robson's Ten-Group Classification System (10-group classification) provides a clinically relevant classification of CS rates that provides a useful basis for international comparisons and trend analyses.
It is important to create relevant classifications of specialized cell types and to distinguish between functional physiology and pathology or disease.
For the non-SEER group, a prostate cancer diagnosis was based on the presence of the relevant International classification of diseases, 9th revision, (ICD-9) code (Table 1) in the first position in any inpatient, outpatient or physician Medicare claim.
Mothers with diabetes were identified from the Patient Register and from the Cause of Death Register (defined according to the relevant International Classification of Disease (ICD) codes ICD-7: 260; ICD-8: 250; ICD-9: 250, 648W, 648A; and ICD-10: E10-E14, O24) between 1964 and 2006.
For our mortality analysis, the death certificate and underlying cause of death, as coded by the Office for National Statistics using the relevant International Classification of Disease, were obtained.
Health priority areas were selected using the relevant International Classification of Disease (ICD-10-AM) codes [see Additional file 1].
