Dynamic contrast in dual-beam optical coherence tomography imaging of human skin.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Imaging of metabolic and cellular activity in living tissue is of high interest and represents a prerequisite for an understanding of environmentally induced tissue changes. In this work, we present a dual-beam optical coherence tomography (OCT) instrument that is used to investigate dynamic processes of human skin samples with two different transverse resolutions. The amplitude and the phase of the OCT signal in both channels are exploited to assess these processes. The temporal evolution of dynamic processes in living skin tissue is analyzed and used to provide increased image contrast. This allows for a clear separation between the stratum corneum, the living epidermis, and the dermis that is otherwise not visible in standard OCT images of the system. Thereby, better dynamic contrast was observed using the higher resolution images. The reproducibility of the method is tested, and the imaging results are compared with data from fixated skin samples (where no dynamics were found within the living epidermis) and histology.
