Energy-dense enteral nutrition,
does it really help with Reduced 90-day mortality in mechanically ventilated critically ill adults?
research showsThe grade is D. In the actual TARGET analysis of 90-day mortality, deaths were 523/1,948 (26.8%) with energy-dense nutrition versus 505/1,966 (25.7%) with routine nutrition, an absolute difference of +1.2 points, RR 1.05 (95% CI 0.94 to 1.16), p=0.41. This large double-blind trial found no survival benefit, but its power assumption was not a validated minimum important difference, so meaningful benefit was not definitively excluded; the result is D with 34 points.
ads claimThe trial does not support a claim that meeting a higher calorie target improves survival. A denser formula increased calorie delivery at the same target rate, but did not reduce 90-day mortality.
Useful facts when choosing a product
- The trial formulas contained 1.5 and 1.0 kcal/mL, with similar protein concentrations of 56 and 55 g/L.
- Trial nutrition continued for up to 28 days or until enteral feeding stopped, death, or ICU discharge.
- Both formulas supplied by Fresenius Kabi were randomized intervention materials, not assessment tools.
What the research actually shows
There were 4,000 randomization events, with three patients randomized twice, leaving 3,997 randomized patients. The prespecified modified intention-to-treat population was 3,957, 1,971 versus 1,986; the actual 90-day primary analysis included 3,914, 1,948 versus 1,966. Australia's NHMRC and New Zealand's Health Research Council provided grants. Fresenius Kabi Deutschland provided in-kind supply and delivery of both trial formulas, which were intervention materials rather than assessment tools. The company reviewed and commented on the manuscript, while investigators designed, conducted, analyzed, and decided to submit the trial. Axis 6 B0 evidence ① Allocation concealment: "Concealment of the treatment assignments was maintained with a secure, Web-based randomization system, which was accessible 24 hours a day." ② Blinding: "We conducted an investigator-initiated, randomized, double-blind, pragmatic trial"; "The formulations were indistinguishable in color and packaging." ③ Analysis population and missing data: "All analyses were conducted with the use of a modified intention-to-treat principle."; "No imputation was used to estimate missing data, and analyses were based on all available data with numbers of available observations reported." ④ Prespecified primary endpoint: "The primary outcome was all-cause mortality within 90 days after randomization." — consistent with registration NCT02306746
Why this is classified as D (34)
A large double-blind hard-outcome trial found no survival benefit and left benefit possible, giving D with 34 points. Secure web allocation, blinding, prespecified modified intention-to-treat analysis and missing-data handling, and a registry-consistent primary endpoint were documented.
Counterpoint. This verdict is limited to 90-day survival. Specific deficiency states, protein dose, and long-term functional recovery are separate questions.
Rejudgment record. Cross-check applied — Centers the actual 3,914-person 90-day mortality analysis and its absolute and relative estimates while accounting for mixed funding, in-kind intervention supply, and four directly documented trial-quality requirements
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I1 | Mixed funding sources |
| Effect size | E0 | Null |
| Precision | C0 | The confidence interval leaves room for benefit |
The scoring table and the verdict agree (D).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Energy-dense enteral nutrition reduces 90-day mortality | D | Mortality was 26.8% versus 25.7%, RR 1.05, with no benefit. |
| Energy-dense enteral nutrition increases delivered calories | B | It delivered a mean 601 kcal/day more from trial nutrition. |
