I know the thread How to hide references from navigation bar in beamer class? I do not want to hide it but suppress it such that it does not come out. I got this complication in this thread Set limit on number of authors in citation call-out when using the IEEEtranN bibliography style.
Code
\documentclass{beamer}
\usepackage{natbib}
\useoutertheme{Berlin} % I think not necessary because otherwise just default which is fine
\begin{document}
\begin{frame}
\frametitle{Cesarean Section and Epidemiology}
\begin{itemize}
\item First Modern C-section by Ferdinand Adolf Kehrer 1881. \cite{history_c_section}
\end{itemize}
\bibliographystyle{IEEEtranN}
\bibliography{task}
\end{frame}
\end{document}
task.bib
@book{ history_c_section,
author = "Dadebo, Dr. Benjamin",
year = 2012,
title = "Begat By God: Understanding the Concept of Being Born Again",
publisher = "Xlibris Corporation",
pages = "31–",
note = "ISBN 978-1-4771-0612-9"
}
I think the top-bar is handled like section by beamer. Normally, I do \section*{My Name is Masi} to hide the numbering. Probably, a similar procedure could work somehow with BibTeX.
Complication
How to Suppress the top bar refereces in BibTeX of Beamer?

beamer"themes"; thus, no bar along the top of the page is being generated by the MWE. Please edit your MWE to make it generate an info bar along the top of the page. – Mico Feb 26 '16 at 06:04
