"Conjugated Equine Estrogen and Risk of Benign Proliferative
Breast Disease: a Randomized, Controlled Trial" by Rohan et
al. [J Natl Cancer Inst 2008; 100(8):563–571]. The information
presented in the third paragraph of the Results section on the
histologic sections reviewed for the study should have read
as follows: "Of the sections reviewed, 71 were from biopsies
that occurred outside the trial period and 39 had no breast
tissue; these 110 sections were excluded from further consideration.
The 520 eligible sections that were reviewed were from 478 women.
Of these women, 3 were excluded due to censoring (so that the
corresponding section was excluded from further consideration),
3 had no pathological diagnosis, 240 had a non-proliferative
lesion, and 232 had an incident benign proliferative lesion."
Because events and event-times were accounted for appropriately
in the analysis, the total numbers of each type of specimen
(no pathological diagnosis, non-proliferative lesion, or incident
benign proliferative lesion) were unchanged and the results
presented in the manuscript are not affected by this correction.
The authors regret the error.
