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

Extensive solar ultraviolet B (UVB) exposure of the skin results in inflammation and oxidative stress, which may contribute to skin cancer. Natural products have attracted attention for their role in the effective treatment of cutaneous neoplasia. Juglanin is purified from the crude extract of Polygonum aviculare, exhibiting anti‑oxidant, anti‑inflammatory and anti‑cancer activities. Jugalanin was used in the current study to investigate whether it may ameliorate UVB irradiation‑induced skin damage by reducing oxidative stress and suppressing the inflammatory response in vivo and in vitro. In the present study, hairless mice were exposed to UVB irradiation in the absence or presence of juglanin administration for 10 weeks. The findings indicated that juglanin inhibited UVB‑induced hyperplasia and decreased infiltration in the skin of mice. UVB exposure‑induced oxidative stress in mice and cells was inhibited by juglanin via enhancing anti‑oxidant activity. Additionally, juglanin markedly reduced pro‑inflammatory cytokine release, including cyclic oxidase 2, interleukin‑1β and tumor necrosis factor‑α, triggered by chronic UVB irradiation. Juglanin‑ameliorated skin damage was associated with its suppression of mitogen activated protein kinases (MAPKs), including p38, extracellular signal regulated 1/2, and c‑Jun N‑terminal kinases, as well as nuclear factor (NF)‑κB signaling pathways, which was dependent on nuclear factor‑E2‑related factor 2 (Nrf2)‑modulated reactive oxygen species generation. Taken together, these data indicate that juglanin protected against UVB‑triggered oxidative stress and inflammatory responses by suppressing MAPK and NF‑κB activation via enhancing Nrf2 activity.
