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