Serum Creatine Levels as a Predictive Factor for Postoperative Cerebrovascular Events in Patients With Moyamoya Disease.
Article in Brain and behavior, 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
backgroundCreatine is essential for energy storage and transfer within and outside cells. However, its relationship with cerebrovascular disease has not been fully explored. This study examined the association between serum creatine levels and postoperative cerebrovascular events, including transient ischemic attack (TIA), ischemic stroke, and hemorrhagic stroke, in patients with moyamoya disease (MMD).
methodsSerum creatine and disodium creatine phosphate levels were quantified in 352 patients with MMD using liquid chromatography-tandem mass spectrometry. Kaplan-Meier (KM) curves were used to analyze the impact of serum creatine levels on cerebrovascular event risk, whereas univariate and multivariate Cox regression analyses were used to identify predictors of postoperative outcomes. A prognostic nomogram was developed to predict stroke-free survival at 12, 24, and 36 months postoperatively.
resultsIn patients with MMD, serum creatine showed a negative correlation with creatinine (r = -0.22; p < 0.001) and homocysteine (r = -0.10; p < 0.05) but not with disodium creatine phosphate (r = -0.08; p = 0.15). When patients were divided into high and low groups based on the median serum creatine concentration, KM curve analysis revealed that patients in the high concentration group had a lower relative risk of cerebrovascular events than those in the low concentration group (hazard ratio: 0.55; 95% confidence interval, 0.33-0.94; p = 0.026). Furthermore, when patients were categorized into three levels based on creatine concentration, the overall KM curve analysis showed a significant difference (p = 0.038), such that the highest creatine concentration group (third tertile) showed a significantly reduced risk compared with the lowest concentration group (first tertile; p = 0.04).
conclusionLower preoperative serum creatine levels were associated with a higher risk of postoperative cerebrovascular events in patients with MMD. Therefore, creatine supplementation may be an effective means of preventing adverse outcomes in patients with MMD.
