BMC Medical Research Methodology, 2010 BackgroundData on survival endpoints are usually summarised using either hazard ratio, cumulative number of events, or median survival statistics. Network meta-analysis, an extension of traditional pairwise meta-analysis, is typically based on a single ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Hazard Ratio Estimation in Small Samples
Statistics in Biopharmaceutical Research, 2018 When comparing survival times between groups in the setting of proportional hazards, the Cox model is typically used for estimation and inference, the latter based on large sample considerations. Mehrotra and Roth introduced a generalized log-rank (GLR) method for better statistical efficiency in estimating relative risk in small samples.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Circulating histones as clinical biomarkers in critically ill conditions
FEBS Letters, EarlyView.Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Clinicopathological Presentation, Prognosis, and Overall Survival of Primary Extra Nodal Lymphomas
Medical Journal of Dr. D.Y. Patil VidyapeethIntroduction: Primary extranodal lymphoma (PENL) originates from extranodal organs or tissues. Approximately 25–40% of NHL arise primarily from sites other than lymph nodes.

A hazard ratio was estimated by a ratio of median survival times, but with considerable uncertainty [PDF]
Journal of Clinical Epidemiology, 2014 To evaluate the empirical concordance between the hazard ratio (HR) and the median ratio (MR) in survival cancer studies.We selected all cancer survival articles from the New England Journal of Medicine published between 2000 and 2010. The qualitative concordance was estimated by the proportion of measured pairs in which the treatment effects for the ...
