• Adding a wildcard symbol may retrieve word variants: ((((((\ practical guidebook to biostatistical and epidemiology.\ ) OR (\ practical guidebook to biostatistical and epidemiology.\ ))) OR (((\ practice guidebook to ((((biostatistics OR statistics) OR biostatistical) OR biostatistical) OR biostatistical) and epidemiology.\ ) OR (\ practice guidebook to biostatistical and epidemiology.\ ))))) OR (\ practical guide to statistical and epidemiology.\ ))*.
