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