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

Regulating solar heat gain is crucial for reducing heating, ventilation, and air conditioning (HVAC) energy consumption in buildings and promoting sustainable responses to climate change. Current thermochromic materials suffer from poor durability and limited optical modulation. Here, the study presents a durable thermochromic coating based on an organogel-higher alkane (HA) composite. The reversible phase change of HA within the organogel induces light reflection, scattering, and diffraction, while carbon black particles enhance the absorptance modulation, achieving a maximum change of 0.35. For practical application on cement, where a highly reflective layer is applied beneath, the absorptance modulation can reach 0.25, exceeding reported values for other thermochromic systems that could be applied to the roof or wall. The material withstands prolonged UV exposure and repeated thermal cycling without degradation, making it suitable for real-world applications. Simulations incorporating a reflective underlayer demonstrate potential annual HVAC energy savings of up to 3% across diverse climate zones. This work introduces a robust, scalable, and season-adaptive thermochromic coating for sustainable building energy management.
