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