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