OptoCENTAL: a standardized, bench-testing platform based on phantoms for validating optical systems aimed at clinical monitoring of the placenta.
Article in Journal of biomedical optics, 2026. 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
Significance: Optical imaging and spectroscopy solutions, such as near-infrared spectroscopy (NIRS) and diffuse optical tomography, have the potential to provide compact, bedside monitoring of the placenta in the clinic, thanks to recent advancements in miniaturization and wireless wearability. This would provide neonatologists with continuous assessment of the pregnancy status in real time, as well as tools to possibly predict delivery outcomes. Aim: Numerous challenges are associated with validating the performances of any optical system in providing the above goals, particularly the required depth sensitivity and accuracy to target the placenta Approach: We present here OptoCENTAL, a standardized platform based on multiple optical phantoms, from digital, through solid to liquid, for versatile bench testing, characterization, and validation of any photonics solution and instrumentation that aims at Results: Exemplary applications of the OptoCENTAL platform on different types of optical systems, from wearable, continuous-wave devices to broadband and time-domain NIRS systems, demonstrate the flexibility of its procedures to be implemented with any setup, allowing users to compare performances across different solutions. The results also show the capability of OptoCENTAL to provide quantitative assessment of the major features required by any photonic solution for providing effective and efficient monitoring of the placenta, including basic instrument performances, quantification of monitoring accuracy, and depth sensitivity. Conclusions: OptoCENTAL represents the first-of-a-kind effort in standardizing bench-testing and validation of optical imaging and spectroscopy methods in the framework of placental clinical applications, further advancing the translation of such modalities into hospitals, as well as toward future certification and commercialization of such technologies.
