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