1 · What the graph read from it

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.

2 · The registry

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

Vascular endothelial cells (ECs) play significant roles in regulating circulatory functions. The shear stress resulting from blood flow modulates EC functions by activating mechano-sensors, signaling pathways, and gene and protein expressions. Shear stress with a clear direction resulting form pulsatile or steady flow causes only transient activation of pro-inflammatory and proliferative pathways, which become down-regulated when such directed shearing is sustained. In contrast, shear flow without a definitive direction (e.g., disturbed flow in regions of complex geometry) causes sustained molecular signaling of pro-inflammatory and proliferative pathways. The EC responses to shear flows with a clear direction involve the remodeling of EC structure to maintain vascular homeostasis and are athero-protective. Such regulatory mechanism does not operate effectively when the flow pattern is disturbed. Therefore, the branch points and other regions of the arterial tree with a complex geometry are prone to atherogenesis, whereas the straight part of the arterial tree is generally spared. Understanding of the EC responses to different flow patters helps to elucidate the mechanism of the region-specific localization of atherosclerosis in the arterial system.
