• ConclusionsConclusions– PubMed does not provide adequate access to Egyptian research in these areasgyp
– No requirement for PubMed to include all studies
– Outcomes of Egyptian research may be more difficult to access (especially to decision‐makers outside Egypt)
– Relevant research data may be unread/unreviewed
– A new mechanism is needed to provide comprehensive access

• NCI responsibility for management & maintenance p y g• Outcomes:
– A comprehensive listing of Egyptian research relevant to h fi f hthe five areas of cancer research
– A structure and methodology for extending the database to all areas of Egyptian cancer control
– Visible international profile for Egyptian research– Facilitates systematic reviews of the relevance and methodological quality of researchmethodological quality of research
– More informed research & development agenda (national and international)
ConclusionConclusion
• If clinical research is to be at all useful to clinical practice – it must first be visible
• Research published in developing countries is currently under represented by the leadingcurrently under‐represented by the leading bibliographic databases
• New database needed to ensure outcomes ofNew database needed to ensure outcomes of cancer control research are more easily accessible to decision‐makers (clinicians, researchers policy makers and patients)researchers, policy‐makers and patients)
• New database should be developed and maintained on site in developing countriesp g
