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

introductionIn recent decades, Cold Atmospheric Plasma (CAP) has become increasingly popular in healthcare for managing diseases, especially skin cancer. This study aimed to assess the preclinical safety of an indigenously developed dielectric barrier discharge-CAP (DBD) device and its cytotoxic efficacy against melanoma cells while adhering to OECD 402 guidelines for acute dermal toxicity study. The safety evaluation includes ex vivo studies on mouse peritoneal exudates and in vivo acute dermal toxicity tests on Wistar rats.

methodsThe ex vivo study of mice peritoneal cells treated for up to 120 seconds, showed a survival rate of over 90% up to 90 seconds of CAP treatment for applied voltage 18.6 kV at 20 kHz with no significant difference with control. In the acute dermal toxicity tests, CAP exposure for up to 30 seconds caused minimal inflammatory cell infiltration and no significant Dermal Inflammation Scoring (DIS) (60;1).

resultsThe efficacy study against G361 human melanoma cells showed reduced cell viability by ~50% (MTT assay) upon 30 seconds of CAP treatment for applied voltage 24 kV at 20 kHz through ROS-mediated apoptosis, confirmed by a 3-fold increase in intracellular reactive oxygen species levels and nuclear fragmentation (4',6-diamidino-2-phenylindole staining). Annexin V/PI (propium iodide) staining further revealed ~30% apoptosis after 24 hours of incubation. These findings establish the developed DBD-CAP device is safe for rat skin exposure durations of up to 30 seconds and effective in inducing apoptosis in melanoma cells.

conclusionThis study supports CAP's optimization for clinical applications and its integration with existing therapies for enhanced outcomes. However, further study is needed to examine the possible risks associated with using CAP devices in the biomedical field.
