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
backgroundThe hypobaric hypoxic atmosphere can cause adverse reactions or sickness. The purpose of this study was to explore the preventive effect and mechanism of human umbilical cord mesenchymal stem cells (hUC-MSCs) on acute pathological injury in mice exposed to high-altitude.
methodsWe pretreated C57BL/6 mice with hUC-MSCs via the tail vein injection, and then the mice were subjected to hypobaric hypoxic conditions for five days. The effects of hUC-MSCs on the pathological injury of lung, heart, brain were assessed by biochemical analysis, histopathological testing, quantitative real-time polymerase chain reaction (qPCR), and western blot (WB). Further, transcriptome sequencing was used to screen for the potential therapeutic targets of hUC-MSCs in acute pathological injury, the identified signaling axis was characterized using Apoe
resultshUC-MSCs administration notably prevented and relieved gastrointestinal symptoms and inflammation of lung and heart, increased blood oxygen saturation and serum superoxide dismutase (SOD) level, decreased serum malondialdehyde (MDA) level, rescued lung tissue injury and myocardial mitochondrial disorder, elevated nissl bodies number in brain tissue and reduced the degree of pulmonary and cerebral edema. Furthermore, hUC-MSCs pretreatment reversed the down-regulated Apoe and up-regulated Pdgf-b and p-Erk1/2 in the lung of hypobaric hypoxic mice. Thus, hUC-MSCs protected against acute pathological injury caused by hypobaric hypoxic condition via the Apoe/Pdgf-b/p-Erk1/2 axis, and the identified pathway was confirmed by the negative results of Apoe
conclusionhUC-MSCs possess the preventive effect on acute pathological injury caused by hypobaric hypoxia environment at high-altitude.
