1 · What the graph read from it

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.

2 · The registry

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

Indoor humidity can significantly impact our comfort and well-being, often leading to the use of mechanical systems for its management. However, these systems can result in substantial carbon emissions and energy precarity. This study offers an alternative: using low-carbon materials that naturally buffer moisture to passively regulate the indoor humidity. A geopolymer composite incorporating industrial waste is implemented via binder jet 3D printing technology. The superhygroscopic nature of the material, combined with the optimal geometry of 3D-printed components, unlocks remarkable potential for passive humidity regulation, achieving a moisture buffering value over 14 g·m⁻²·%RH⁻¹. The use of 3D-printed, geopolymer tiles for surface finishing in a library hosting 15 people was shown to improve annual indoor hygrometric comfort by up to 85%, a performance inconceivable with conventional materials and techniques. Additionally, the environmental impact of these tiles is significantly lower than that of a conventional dehumidification system. This study paves the way for merging highly hygroscopic, low-carbon materials with advanced manufacturing techniques to regulate indoor humidity levels and reduce our dependency on mechanical systems.
