To improve the quality and safety of care for people with dementia, this expertise can be the subject of partnerships between caregivers and health care staff. This study was able to point out that today's caregivers have developed more competency than their predecessors. This evolution can be explained by new paradigms of care requiring caregivers to be more involved. Although some caregivers need training, others through their experiences can act upon and provide knowledge. To improve the quality and safety of care for people with dementia, this expertise can be the subject of partnerships between caregivers and health care staff. Gene expression signatures for the prediction of differential survival of patients undergoing anti-cancer therapies are of great interest because they can be used to prospectively stratify patients entering new clinical trials, or to determine optimal treatment for patients in more routine clinical settings. Unlike prognostic signatures however, predictive signatures require training set data from clinical studies with at least two treatment arms. As two-arm studies with gene expression profiling have been rarer than similar one-arm studies, the methodology for constructing and optimizing predictive signatures has been less prominently explored than for prognostic signatures. Focusing on two "use cases" of two-arm clinical trials, one for metastatic colorectal cancer (CRC) patients treated with the anti-angiogenic molecule aflibercept, and the other for triple negative breast cancer (TNBC) patients treated with the small molecule iniparib, we present derivation steps and quantitative and graphical tools f data sets is predicted to be high. The tools presented here should be of general use for building and using predictive multivariate signatures in oncology and in other therapeutic areas. The t
