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