• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decreased gastric processing ) OR ( decrease lesions decrease to decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decreased gastric processing ) OR ( decrease lesions decrease to decrease ))*.
