Flag indicating whether the PubMed Publication Type tags for this article are consistent with that of a primary research article. To be counted as an Article, a paper's Publication Types must include at least one type from the qualifying list (e.g. Journal Article or Clinical Trial) and cannot contain any from the disqualifying list (e.g. Editorial or Review) (see table below).
Based on manual curation of a random sample of articles published in 2013, this classification strategy yields 92% accuracy. 8% of 'article' assignments on average were incorrect, while 5% of 'non-article' assignments were incorrect. Most errors tend to occur in journals that are not indexed in MedLine, suggesting that persons whose publication records are concentrated in non-MedLine journals may have disproportionately high error rates in this classification schema.
