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