Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. 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
This study presents a comprehensive study of a driven degenerate Λ-type three-level laser system utilizing a squeezed vacuum reservoir to enhance its performance. The interaction between the laser medium and the squeezed vacuum field is analyzed, revealing significant improvements in coherence and output characteristics. By employing a Λ-type configuration, we explore the population inversion dynamics and the role of squeezed states in reducing quantum noise, ultimately leading to enhanced laser stability and efficiency. Theoretical models are developed to describe the laser dynamics, incorporating the effects of external pumping and the non-classical properties of the squeezed vacuum. Numerical simulations demonstrate that the incorporation of squeezed states leads to a notable increase in the laser's output power and spectral purity compared to traditional systems. These findings suggest that squeezed vacuum reservoirs can serve as a powerful tool for advancing the capabilities of three-level laser systems, with potential applications in quantum optics, communication technologies, and precision measurement.
