Most studies utilise comparisons of cancer cell lines or cancer tissue samples with normal tissue to identify cancer-associated epigenetic aberrations that occur during tumour development.
A process of axial coding will be utilised where comparisons will be drawn between emerging themes.
Analysis of GD1-positive versus GD1-negative samples utilised multiple comparisons and a Bonferroni correction was applied.
Paired-samples t-test or Mann-Whitney U tests were utilised for comparisons between groups (depending on the normality of the distributions).
A crash test dummy chest calibration pendulum was utilised for comparison.
The earliest GEP studies utilised class comparison to identify differentially expressed genes among morphologically defined gliomas.
A master image gel (MIG) was integrated with the two duplicate gels of each strain and was utilised for comparison.
Four studies utilised a comparison group that was a waiting list control group with no professional contact at all [ 13, 17- 19].
Both of these methods utilise comparison of the position of bony anatomy within the treatment field, but due to the predominance of Compton scatter rather than the photoelectric effect at treatment energies, bone may be poorly visualised.
Subsequently, using B-CLL, FL and DLBCL tumor samples we have utilised cohort heterozygosity comparisons to localise LOH candidate regions in these subtypes of non-Hodgkin's lymphoma.
