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