Based on power analyses and assuming a conservative intracluster correlation coefficient, 1289 children were needed to detect a 25% difference in rates between the two groups of the cluster trial.
The two groups of patients, obtained after hierarchical cluster analysis using stromal genes, differed significantly in their overall survival (P = 6.74e-05), indicathat thet the breast stromal genes had survival-predictive value for breast cancer patients.
The distinction between the two groups of meningiomas by array CGH cluster analysis apparently reflects the existence of at least two main types of genetic mechanism for meningioma tumorigenesis.
The two groups of mice separated into completely distinct clusters based on autoantibody reactivity to these autoantigens.
The two groups of samples scattered randomly without forming separable clusters (Fig. 1) when we analysed the three cohorts.
The PLS-DA scores plot demonstrates that the two groups of samples are well separated to two clusters, thus the LUPM group was different from the HUPM group by metabolomics analysis of serum samples.
Interestingly, all datasets, treated with different regimens or untreated, exhibit similar patterns, with the two groups of residues exhibiting most distinctive correlation behavior clustered at similar sequence positions.
A comprehensive analysis of baseline variables of the two treatment groups will be performed to assess the extent, if any, of baseline imbalances between the two groups of clusters/communities assigned to the two treatment groups, both at the individual and at the cluster levels, to determine the need for adjusting analyses.
It is the 'truly' ER-negative tumors that have high basal cytokeratin expression, and the four groups of luminal tumors cluster together in the negative region of the plot.
Furthermore, these two separate datasets correctly classified the three groups of samples using hierarchical cluster analysis.
To be able to study possible similarities and differences in the expression patterns between the three groups of cell lines, we used cluster analyses.
