Define and provide an example for the following design method: Stratified sampling. What would be the mean of this data set: 8, 9, 7, 508, 7, 1, 5, 8, 1? Define and give an example of Qualitative variables. Given the following data set for X and Y: __ X = 27, 32, 49, 22...
Just as average expression of PAM50 genes in tumor cells from snRNA-seq could discriminate tumor subtype, chromatin accessibility in the promoters of PAM50 genes from snATAC-seq showed good segregation of tumors by subtype in the 21 samples (from 21 cases) with both data types available (Fig....

In the TP group, the Kaplan–Meier estimate depicted similar curvatures as those observed in the pre-stratified and ITT populations6(Fig.2a, e), indicating that adjuvant gefitinib achieved a superior DFS. Importantly, the survival curves of the post-categorized HTP and CP populations did not con...
Patients Were Strictly Stratified by RECIST Response and Progression-free Survival The study identified 120 patients (number of biopsies per assay detailed in Figure S1A) treated with anti-PD-1 monotherapy (nivolumab or pembrolizumab; n = 63 patients) or combined anti-CTLA-4 and anti-PD-1 thera...
This archaeometric study aims at characterizing the archaeological finds belonging to the lithic industry from La Calvera rock shelter (Camaleño, Cantabria) and at hypothesizing the possible provenance of each material. The site, located in the mountainous area of Picos de Europa National Park ...
Alterable weight loss presented the highest specificity rates in all the subgroup analysis. Biron criteria showed good specificity and sensibility in the stratified analysis per surgery technique but worse results in the stratified analysis per initial BMI. Figure 5. Sensitivity and specificity (...

clinicopathologic features. Through machine learning based integrative pharmacogenomic analysis, the microRNA biomarkers identify novel therapeutics for stratified application in osteosarcoma. The previously unrecognized osteosarcoma subtypes with distinct clinical courses and response to therapy could be translatable...
