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