Evolution of Reporting P-Values

Open Dataset : Evolution of Reporting P-Values in the Biomedical Literature, 1990-2015

A review of p-values in the biomedical literature from 1990 to 2015 by researchers from ISC-PIF and Standford University shows that these widely misunderstood statistics are being used increasingly, instead of better metrics of effect size or uncertainty.

To complement the JAMA paper, we relase the full set of extracted P-values in Pubmed and PMC full text. This dataset contains 4,572,043 P-values extracted in 1,608,736 Pubmed abstracts and 3,438,299 P-values extracted in 385,393 PMC full-text articles in the period 1990-2015.

It is available for download on the ISC-PIF Dataverse
