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

Background: Oral mucositis (OM) affects the quality of life and therapeutic outcomes of cancer patients. More effective drugs and methods for treating OM are urgently required for clinical application. Extracellular vesicles can play important roles in cutaneous wound healing. However, their role in OM remains unclear. Our aim was to investigate the function and mechanisms of topical coatings of extracellular vesicles derived from human umbilical cord mesenchymal stem cells (hUC-MSC-EVs) in OM. Methods: HUC-MSC-EVs were isolated by differential ultracentrifugation. We used glacial acetic acid to induce the formation of OM in rats. HUC-MSC-EVs were covered on the OM topically once a day. Rats' body weights were measured on alternative days. The healing degree of OM was evaluated with macroscopic observations and histological examinations. We also analyzed the mechanisms of hUC-MSC-EVs when promoting the healing of OM. The expression levels of NF-κB, IL-6, TNF-α, and IL-1β in mucosal tissue were evaluated using immunohistochemistry. Results: The median healing time of OM in the blank control, rhaFGF, 0.25 µg/µL EVs, 0.75 µg/µL EVs, and 1.50 µg/µL EVs groups was 14, 11, 10, 7, and 11 days, respectively. The most significant effect of hUC-MSC-EVs in promoting healing was at the concentration of 0.75 µg/µL. The median healing scores in the 0.75 µg/µL EVs group were 4 on day 5 and 3 on day 8 (*P<0.05 Conclusions: Our results showed for the first time that coating hUC-MSC-EVs topically can promote healing of OM because it may inhibit the activation of the NF-κB signaling pathway.
