Reviewer's report:
This study was to test an effect of peer education on improving knowledge about
breast cancer and breast self examination in female Nigerian adolescents. 
It is valuable study to improve knowledge through cost-effective peer education. 
However I have a concern about inconsistency between study purpose, design,
and statistical analysis.
This study was likely to use one group pre- and post-test design for seminar
cohort and school cohort to test the effect of peer education upon your study
purpose. 
For this study design, you should have used a statistical test of McNemar test for
pre and post-test with same population for nominal variables.
However, your Table 1, 2, and 3 showed that school cohort's sample size
between pre and post test was not same : 1310 for pretest and 1201 for posttest.
It was not the paired data set at all. 
I want authors to select sample who participated in both pre- and posttest and
then run statistical analysis again with appropriate method to answer you
research questions.
