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