Inverse relationship between circulating sphingosine-1-phosphate and precursor species and coronary artery calcification score in type 2 diabetes.
Observational study in Cardiovascular diabetology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02431234 (Study of the Mechanisms of the Arterial Calcification of the Members Subordinates in the Diabetes), which is not on this map. Cited by 6 papers.
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.

Abstract
backgroundSphingosine 1-phosphate (S1P) is a key mediator of lipid signaling with strong immunomodulatory and anti-inflammatory effects. Circulating S1P levels including S1P in high-density lipoproteins (HDL) were demonstrated to be inversely associated with cardiovascular diseases (CVD). However, no studies are available regarding a potential implication of S1P on the risk of CVD in type 2 diabetes (T2D). The objective of this study is to determine if the increased CVD risk in T2D may involve an alteration of circulating S1P species as well as their precursors.
methodsA total of 168 and 31 patients with T2D (154 men and 45 women) with available Coronary artery calcification (CAC) score from the DIACART and CERABIAB cohorts, respectively, were included in the study. Quantification of S1P species and their precursors was carried out by LC-MS/MS in plasma and isolated HDL. CAC score was modeled as a binary variable (0/1 below or equal/above 100) using CAC < 100 for reference. S1P species or precursors were modeled as binary variables dichotomized at the median (0/1: below or equal/above the median). The relationships between S1P species and CAC score modeled as a binary variable (below or equal/above 100) was evaluated by linear regression analyses. In vitro experiments were conducted to evaluate the contribution of HDL-S1P content on anti-inflammatory properties of HDL particles.
resultsMultivariate analysis revealed that plasma S1P levels, especially d18:1-S1P, and sphingosine in HDL were inversely associated with the high risk of CVD (CAC > 100) in patients with T2D. Clustering of HDL according to their concentration in S1P species and their precursors revealed that S1P-impoverished HDL is a major feature of patients with a CAC > 100. In vitro analysis of monocyte adhesion and inflammation in human umbilical vein endothelial cells as well as inflammatory phenotype of human macrophages demonstrated that low HDL-S1P exhibited impaired anti-inflammatory properties in comparison to high HDL-S1P.
conclusionThis study unraveled that circulating S1P and their precursors are biomarkers of coronary atherosclerosis in T2D, which may underlie the lower abundance of S1P and anti-inflammatory activities of HDL. Trial registration ClinicalTrials.gov number, NCT02431234.
