Jaul 2006.

Methods	Observational prospective cohort study. Followed up for 17 months.
Participants	88 Israeli psychogeriatric inpatients aged 79 ± 9 years. Not all patients were demented (in the tube fed group 68% had dementia). There were significantly more patients in the tube feeding group that were demented (P value 0.002), female (P value 0.019) and the group was older (P value 0.009).
Interventions	62 were fed by nasogastric tube, and 26 orally fed. Indications for tube feeding included difficulty swallowing, refusal to eat and decreased level of consciousness.
Outcomes	Outcomes measured at follow‐up were pressure ulcers, survival time and mortality. In the tube fed group 21% had pressure ulcers at follow‐up, in the orally fed group 42% had. During follow up 25 (40.3%) of the tube feeding group died. The median survival time was 250 days, survival in the orally fed group was 40 days.
Notes	Limitations: both groups contained a mixed group of psychogeriatric patients limiting strength of any analysis.
