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