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