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