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