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