Method

How we check figures

  1. Find the original publisher. We trace each figure to the organization that first published it.
  2. Fetch the page. We open the original page or file and read the figure there.
  3. Read the sample and method. We note who was counted, how, and when.
  4. State the limit. We write what the figure does not show, next to the figure.
