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