Reduction of greenhouse gas emissions using the endoscope with a light-emitting diode light source.
Article in Endoscopy international open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and study aims: Light-emitting diodes are being developed as a light source for an endoscope system instead of xenon lamps, contributing to improved diagnostic capability. This system also has the advantage of consuming less power than a conventional endoscope system using xenon lamps. Power consumption associated with endoscopy is an important factor in reducing greenhouse gas emissions. This study estimated the reduction in greenhouse gas emissions by using a light-emitting diode endoscope system. Methods: We calculated the power consumption and carbon dioxide emission reduction of the light-emitting diode endoscope system in comparison with a conventional endoscope system using a xenon light source. Calculations were based on actual data regarding operating time and the annual number of endoscopic procedures at Jichi Medical University Hospital. Estimates were also extended to a nationwide scale. Results: If each type of endoscope system were used for all endoscopic procedures, the light-emitting diode endoscope system would reduce power consumption by 49% compared with the xenon endoscope system, resulting in a total power reduction of 838.7kWh, equivalent to 394.2 kg of carbon dioxide emissions. In Japan, the total power consumption would be reduced by 53%, corresponding to a total power reduction of 428,628.8 kWh, equivalent to 201,455.5 kg of carbon dioxide emissions. Conclusions: We estimated the effect of reducing carbon dioxide emissions using the light-emitting diode endoscope system. Wider adoption of the light-emitting diode endoscope system is expected to contribute to usefulness of endoscopic diagnosis and reduction in environmental impact.
