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