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