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