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