The impact of nutritional intervention and resistance training on muscle strength and mass in healthy older adults-a comparative analysis.

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
Objective: A growing body of evidence confirms that nutritional supplementation strategies combined with resistance training can enhance muscle strength and mass in older adults. However, the optimal supplementation approach remains unclear. This study aimed to evaluate the comparative efficacy of different nutritional interventions combined with resistance training on muscle strength and mass in healthy older adults and determine the optimal strategy. Methods: A systematic search was performed across three major biomedical databases (PubMed, Web of Science, and EMbase) to identify randomized controlled trials (RCTs) investigating the effects of nutritional supplementation combined with resistance training on muscle strength and mass in healthy older adults. A total of 19 eligible RCTs were included. The search covered literature from database inception to April 2025. Two researchers independently screened studies against predefined eligibility criteria and assessed methodological quality using the Cochrane risk-of-bias tool. Stata 18.0 was used to conduct network meta-analysis. Conclusion: Compared with resistance training alone, protein supplementation combined with resistance training significantly enhanced muscle strength [Standardized Mean Difference (SMD) = 0.45, 95% confidence interval (CI): 0.20,0.69; surface under the cumulative ranking curve (SUCRA) = 98.7%] and muscle mass [Mean Difference (MD) = 0.37, 95%CI: 0.04,0.70],whereas creatine supplementation demonstrated non-significant effects on muscle strength versus training alone (SMD = 0.03, 95% CI: -0.35,0.42) but yielded the most pronounced improvement in muscle mass (MD = 2.18, 95%CI: 0.92,3.44; SUCRA = 99.9%), outperforming both protein and β-hydroxy-β-methylbutyrate (HMB) interventions, with HMB supplementation critically failing to demonstrate significant benefits for muscle strength (SMD = -0.22, 95%CI: -0.57,0.12) or mass outcomes (MD = 0.05, 95%CI: -0.33,0.44).
