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