Synergistic Effects of Protein Intake and Exercise on Biomarkers of Sarcopenia: A Systematic Review.

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
Sarcopenia, defined as the progressive decline of muscle mass, strength, and function, severely compromises autonomy and quality of life in older adults. This systematic review evaluated synergistic effects of protein supplementation combined with resistance exercise on biochemical and functional biomarkers of sarcopenia. The search for scientific evidence was conducted in PubMed, Scopus, ScienceDirect, and Cochrane databases (2019-2025), applying explicit inclusion and exclusion criteria, like only randomized controlled trials in humans, published in English, Spanish, or French, were included to ensure high-quality evidence. After selection, the risk of bias of the articles was assessed according to the Cochrane Handbook for Systematic Reviews of Interventions. Seven randomized controlled trials, with a total of 260 participants, met the eligibility criteria. Interventions combining resistance exercise three times per week at 60-80% of one-repetition maximum with daily protein supplementation of at least 15 g, mainly from dairy sources, showed synergistic effects. Improvements were observed in inflammatory and anabolic biomarkers, with reductions in myostatin, activin, and IL-6, and increases in IGF-1, follistatin, and IL-10. Functional outcomes included gains in muscle strength, fat-free mass, and muscle fiber cross-sectional area. Despite heterogeneity in duration and sample size, findings support this combined approach as a promising and clinically applicable strategy to prevent and treat sarcopenia. No external funding was received, and the review is registered in PROSPERO (CRD42025640989).
