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