A study led by WVU epidemiologist Bethany Barone Gibbs found that alternating sitting and standing at work reduces sedentary behavior but has no effect on lowering blood pressure. Prolonged static standing may even have negative effects on cardiovascular health due to a physiological mechanism called the muscle pump.
The study proposes moving beyond binary interpretations of statistical results, encouraging unfiltered reporting and cumulative evidence-based conclusions. Authors argue that NHST can lead to biased research practices and distorted literature.
A new study found that 'gaps' within DNA protein and sequence alignments can provide valuable information about nucleotide and amino acid substitutions. The finding is particularly relevant for studying distantly related species.
The launch of Neurotrauma Reports Null Hypothesis journal aims to promote balance in academic publications by publishing well-performed replication and negative studies. The initiative encourages researchers, funders, and publishers to report on important negative results with the same priority as positive results.
Researchers developed a statistical model to understand the frequency and severity of megadroughts in the western US. They analyzed tree ring evidence from 800 to 1300 A.D. and found that megadroughts occur naturally, with some events potentially linked to solar activity or other non-climatic factors.
A recent study by researchers at Stanford University School of Medicine found that p-values are being misapplied in millions of biomedical journal articles, leading to the illusion of credible research. The study suggests that this widespread misuse may not indicate an improvement in research conduct or data analysis.
