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