The Role of Electrolytes in Muscle Pain Syndromes: A Systematic Review and Meta-Analysis With Implications for Temporomandibular Disorder.

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
backgroundTemporomandibular disorders (TMDs) are a major cause of chronic orofacial pain, with myalgia of the masticatory muscles being central to symptom burden. Electrolyte modulation, particularly magnesium, may influence neuromuscular excitability and nociceptor sensitization, but no systematic review has synthesized the evidence for muscle pain syndromes or its relevance to TMD.
objectivesTo evaluate the efficacy of electrolyte supplementation (magnesium, sodium, calcium, and potassium) in reducing muscle cramps and myalgia, and to explore the biological plausibility and potential extrapolation to TMD-related myofascial pain.
methodsThis systematic review followed PRISMA guidelines and was prospectively registered in PROSPERO (CRD420251120631). PubMed/MEDLINE, Embase, and Cochrane CENTRAL were searched from January 1995 to August 2025. Randomized or quasi-randomized trials of electrolyte supplementation for cramps or myalgia were eligible. Data extraction and risk-of-bias assessment (RoB 2 tool) were performed independently by 2 reviewers. Meta-analyses used random-effects models in R (v4.4.3) and Python (v3.11).
resultsThirteen trials were included. Magnesium was most frequently studied (10 RCTs). In pregnancy-associated cramps (4 trials, N≈364), magnesium significantly reduced cramp frequency compared with placebo (pooled RR 1.35, 95% CI: 1.05-1.74, P = .02). In nocturnal or persistent leg cramps in adults (4 trials, N≈396), no significant effect was found (MD -0.42 cramps/week, 95% CI: -1.15 to 0.31, P = .26). Intravenous magnesium showed no benefit in older adults, but a perioperative trial demonstrated reduced fasciculations and postoperative myalgia. Sodium-based solutions reduced cramp susceptibility in exercise and cirrhosis, while calcium and potassium lacked supportive evidence. Risk of bias was generally low to moderate.
conclusionMagnesium supplementation benefits pregnancy-related cramps but shows inconsistent effects in other populations. Sodium-based interventions are context-specific, and calcium and potassium remain unsupported. Magnesium is the most plausible candidate for translation to TMD myalgia, warranting targeted clinical trials.
