Low versus standard calorie and protein feeding and renal dysfunction in ventilated adults with shock: a NUTRIREA-3 post hoc analysis.
Trial report in Intensive care medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe optimal intake of artificial nutrition in critically ill patients remains unclear. While calorie and protein intakes affect glomerular function in patients with chronic kidney disease, their relation to renal function at the acute phase of intensive care is insufficiently documented. We aimed to study associations of a low-calorie and low-protein diet with renal outcomes in critically ill patients.
methodsThis post hoc analysis of the NUTRIREA-3 randomized-controlled trial included 3036 mechanically ventilated patients with shock. Calorie and protein intakes during the first 7 days were either low (6 kcal/kg and 0.2-0.4 g protein/kg/d) or standard (25 kcal/kg and 1.0-1.3 g protein/kg/d). The primary outcome was the incidence of acute kidney disease (AKD) during the ICU stay (up to ICU discharge or day 90 after inclusion, whichever occurred first).
resultsAKD during the ICU stay occurred in 669 (44.6%) low-group patients and 691 (46.1%) standard-group patients (hazard ratio, 0.97; 95% CI 0.88-1.07; P = 0.53). The highest urea level and the urea level at ICU discharge were significantly lower in the low group (P = 0.002). No differences were found for renal replacement therapy requirements or other renal outcomes. The results were similar in patients with early kidney dysfunction, severe organ failures, or end-stage chronic kidney disease.
conclusionIn critically ill patients with shock, early low-calorie and low-protein nutrition for 7 days was not associated with worse renal outcomes or mortality compared to standard feeding, even in patients with preexisting renal dysfunction.
