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
Atherosclerosis (AS) is a chronic inflammatory disease caused by oxidative stress and the oxidation of low‑density lipoprotein (LDL). Xylitol, a widely used sugar substitute, has antioxidant potential; however, its effects on LDL‑induced oxidative stress in AS remain unclear. Using western blot, reverse transcription‑quantitative PCR, flow cytometry and so on, the present study investigated the role of xylitol in mitigating oxidative stress induced by high levels of LDL in Tohoku Hospital Pediatrics‑1 (THP‑1) human monocytic cell line), a model for studying AS. Xylitol significantly alleviated high LDL‑induced oxidative stress in THP‑1 cells and decreased reactive oxygen species levels, malondialdehyde content and the expression of NADPH oxidase family enzymes. Concurrently, xylitol enhanced the activity and expression of superoxide dismutase and increased the glutathione levels. Mechanistically, xylitol activated the nuclear factor erythroid 2‑related factor 2 (Nrf2)/heme oxygenase‑1 (HO‑1) axis by increasing the NADPH/NADP+ ratio via the regulation of the pentose phosphate pathway via the Nrf2 transcription factor. This led to a decrease in LDL oxidative modification in THP‑1 cells (Figs. 6,7). Overall, xylitol attenuates high LDL level‑induced oxidative stress in THP‑1 cells by modulating the Nrf2‑mediated pentose phosphate pathway and activating the Nrf2/HO‑1 axis, highlighting its potential for the prevention and treatment of AS.
