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