• 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 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 to statistical AND epidemiology.\ ))~.
