Nanoscale monitoring of the initial stage of water condensation on a printed circuit board.
Article in Heliyon, 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
Electrochemical migration is a critical factor contributing to failures in electronics due to humidity. When moisture accumulates on conductor-dielectric-conductor systems under bias voltage, electrochemical processes can be triggered, leading to the growth of metallic dendrites that may ultimately result in system failure. Despite its significance, many aspects of electrochemical migration remain unresolved, particularly regarding the physical characteristics of liquid buildup that facilitate dendrite growth and short circuit currents. While there are a few techniques that can measure water adsorption on the nanoscale, most conventional methods focus on water droplets within the size range of visible light wavelengths. In this study, we implemented a combined electrical-optical-ellipsometric measurement on FR-4 printed circuit boards featuring Sn surface finishes. Our experimental setup allowed for the measurement of water condensation across a wide range of thicknesses, while simultaneously monitoring the solder mask and metal electrodes during cooling. The ambient temperature of 25
