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