Comparison of energy intakes in the study groups
| PEN | TEN | |
|---|---|---|
| PEN, partial enteral nutrition; TEN, total enteral nutrition; EAR, estimated average requirement. | ||
| Results are expressed as median (range). Values are based on the three day food diary completed at three and six weeks; those withdrawing from the study were included only if enteral nutrition continued for at least three weeks. | ||
| Total energy intake (kcal/day) | 2380 (1890–3165) | 2190 (1660–3415) |
| Total energy intake as proportion of EAR | 126% (96–142) | 111% (93–153) |
| Proportion of total energy intake as formula | 47% (39–58) | 98% (89–100) |
| Energy intake from formula as proportion of EAR | 51% (48–69) | 111% (93–146) |
