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