• 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.\\\ ))\\ \.
