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: Sphingosine 1-phosphate (S1P) signaling pathway is involved in the pathogenesis of type 2 diabetes (T2D). So, targeting S1P signaling pathway could be considered as potential therapeutic target for T2D. The aim of this study was to investigate the effects of palmitate and chicoric acid (CA) on S1P signaling pathway in peripheral blood mononuclear cells (PBMCs) from newly diagnosed patients with T2D. Materials and methods: 20 newly diagnosed patients with T2D, aged 40-60 years, were enrolled in the study. PBMCs were isolated and then treated as follows: control groups (untreated, treated with BSA 1% for 12 h), CA groups (treated with 50 μM CA for 6 h), palmitate groups (treated with 500 μM palmitate for 12 h), palmitate + CA groups (treated with 500 μM palmitate for 12 h and then treated with 50 μM CA for 6 h). Finally, sphingosine kinase 1 (SPHK1) and sphingosine 1-phosphate receptor 1 (S1PR1) genes expression were evaluated by real-time PCR and S1PR1 protein levels were quantified using ELISA. Results: Palmitate significantly increased SPHK1 and S1PR1 genes expression and S1PR1 protein levels in PBMCs of patients with diabetes. However, CA ameliorates palmitate-increased SPHK1 and S1PR1 genes expression and S1PR1 levels in these cells. Conclusion: These data indicate that CA could be considered as a novel S1P signaling pathway inhibitor through down regulation of SPHK1 and S1PR1.
