Pneumonia free survival (IMAGE) The University of Hong Kong Caption A HKUMed study found that there is little difference in one-year survival probability among advanced dementia patients on nasogastric tube feeding or careful hand feeding (125 days versus 145 days, Graph 1). But those on nasogastric tube feeding have a lower pneumonia-free survival probability compared with those on careful hand feeding (Graph 2).
