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