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