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
Remote ischaemic preconditioning (RIPC) uses brief limb ischaemia to protect distant organs, but the mechanism of travel of the protective signal remains unclear. This study investigated whether endothelial cells (ECs) contribute to RIPC-induced neuroprotection and the underlying mechanisms. Ten healthy volunteers (5 men, 5 women) underwent RIPC. Blood velocity was measured by Doppler ultrasound, and vascular wall pressure (VWP) was computed from 3D fluid-structure interaction models based on magnetic resonance imaging data. Human microvascular endothelial cells (HMEC-1) were exposed to cyclic higher pressure (CHP) for five cycles. miR-126 expression and promoter DNA methylation were assessed by real-time PCR and bisulfite sequencing. DNA methyltransferases (DNMTs) and global methylation levels were measured. SH-SY5Y neurons were incubated with exosomes from HMEC-1 culture medium and then subjected to oxygen-glucose deprivation/reperfusion (OGD/R). Neuronal viability and apoptosis were evaluated by MTS assay and flow cytometry, and damage by spectrin and cleaved caspase-3 levels. Dicrotic waves were induced in 9 of the 10 participants following RIPC treatment. VWP transiently increased following RIPC. CHP reduced the expression and activity of DNMTs and induced the hypomethylation of the miR-126 promoter sequence in HMEC-1 cells, leading to an increase in miR-126 levels. Exosomes from CHP-treated HMEC-1 cells decreased SH-SY5Y cell injury under OGD/R. RIPC transiently increased VWP in healthy volunteers. The results of this study indicate that CHP treatment may induce the production of neuroprotective molecules by ECs, which may protect against ischaemia/hypoxia-induced neuronal cell injury in vitro, possibly through a CHP-induced effect involving miR-126.
