Excerpt

TABLE 3 · RHESUS-NEGATIVE PHENOTYPE BY DONOR COHORT (n = 344,102)

  cohort A ....... 15.1%
  cohort B ....... 15.4%
  cohort C ....... 14.9%
  cohort D ....... 38.7%   ** see note

  ** cohort D is a self-selected donor group recruited through a single
     campaign and is not representative. Do not compare with A–C.

Transcribed by the data desk. Line breaks follow the original. Bracketed matter is ours.

Editor's note

The statistician's own footnote is the story. We put it in the fourth paragraph and in the headline's qualifier.
