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