Karen Pendergrass

A critical commentary on the systemic risk assessment of tampon metals and the unmeasured question of local vaginal microbial effects.

Read commentary

How we approach a paper

A commentary identifies the paper and its findings, recognizes its strengths, examines methods and interpretation, and explains what further evidence would resolve the open questions. Observations and hypotheses are distinguished, with links to the original sources.

These are independent scholarly commentaries. A post in this section does not imply journal peer review.
