Blood pressure variability and cardiovascular risk in the PROspective study of pravastatin in the elderly at risk (PROSPER) [PDF]
, 2012 Variability in blood pressure predicts cardiovascular disease in young- and middle-aged subjects, but relevant data for older individuals are sparse. We analysed data from the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER) study of ...

What’s the Risk: Differentiating Risk Ratios, Odds Ratios, and Hazard Ratios? [PDF]
Cureus, 2020 Risk ratios, odds ratios, and hazard ratios are three common, but often misused, statistical measures in clinical research. In this paper, the authors dissect what each of these terms define, and provide examples from the medical literature to illustrate each of these statistical measures.

Neutrophil-to-lymphocyte ratio and mortality in the United States general population
Scientific Reports, 2021 The neutrophil-to-lymphocyte ratio (NLR) in peripheral blood reflects the balance between systemic inflammation and immunity and is emerging as a prognostic biomarker in many diseases, but its predictive role for mortality in the general population has ...
