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