• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"\\\"((\\\"practical guidebook to (biostatistical OR ((statistics OR biostatistical) OR biostatistical)) AND epidemiology.\\\\") OR (\\\"((practice guide) OR (practical guide)) to statistical AND epidemiology.\\\\"))\\\"\\"\"".
• Removing quotes may allow a broader search: \ ((\ practical guidebook to (biostatistical OR ((statistics OR biostatistical) OR biostatistical)) AND epidemiology.\\ ) OR (\ ((practice guide) OR (practical guide)) to statistical AND epidemiology.\\ ))\.
