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