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