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