Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

The calculation of a P value in research and especially the use of a threshold to declare the statistical significance of the P value have both been challenged in recent years.

Presurgery 72‐h fasting in GB patients leads to adaptations of plasma lipids and polar metabolites. Fasting reduces lysophosphatidylcholines and increases free fatty acids, shifts triglycerides toward long‐chain TGs and increases branched‐chain amino acids, alpha aminobutyric acid, and uric acid.

Confidence Interval Estimation of Proportion Near Zero or One: A Modeling Secondary Study
Background and Objectives: When computing a confidence interval for a binomial proportion p, one must choose an exact interval that has a coverage probability of at least 1-α for all values of p.

Confidence intervals for the difference and the ratio of Lognormal means with bounded parameters [PDF]
In this paper, confidence intervals for the difference between lognormal means and the ratio of lognormal means with restricted parameter spaces are proposed.

Background Over the past several decades, metrics have been defined to assess the quality of various types of models and to compare their performance depending on their capacity to explain the variance found in real-life data.

Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

Are P values given more importance than they deserve?
In many of the scientific reports, the conclusions are based on the P values. The results are dichotomized based on the cutoff of P values. Often, the clinical significance is ignored over statistical significance.
