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