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