Impact of protein intervention timings on critically ill patients: A systematic review and meta- analysis.
Review in Journal of critical care medicine (Universitatea de Medicina si Farmacie din Targu-Mures), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Critically ill patients experience metabolic alterations that promote muscle atrophy and protein catabolism, increasing morbidity and mortality. While adequate protein provision is essential, the optimal timing remains controversial. Guidelines recommend higher protein targets, but evidence from randomized controlled trials is limited and inconsistent. Aim: To evaluate the effects of early versus late protein supplementation on mortality, complications, and clinical outcomes in critically ill patients. Methods: A systematic review and meta-analysis were conducted using PubMed, Embase, Cochrane Library, and Google Scholar (January 2010-December 2022). Studies comparing early and late protein administration in adult ICU patients were included. Primary outcomes were mortality, infectious complications, overall complications, pneumonia, ICU/hospital length of stay, and mechanical ventilation duration. Results: Thirteen studies (8 RCTs, 3 retrospective, 2 prospective cohorts) involving 10,672 patients were analyzed. Mortality (RR = 0.87, 95% CI: 0.74-1.04, p = 0.11; I Conclusion: Early protein supplementation does not significantly affect mortality or major complications but may shorten ICU stay and ventilation duration. High heterogeneity for some outcomes warrants cautious interpretation.
