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