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

Electrochromic (EC) devices based on structurally designable and color-tunable EC molecules can dynamically regulate light-heat transmittance via the charge-transfer mechanism, yet face challenges of limited near-infrared (NIR) absorption, long-term instability, and restricted modulation modes. Here, we show that π-stacking of heteroaromatic tri-pyridine molecules with a 1,3,5-triazine core (H-TriPy) enhances molecular conjugation, significantly augments NIR absorption, and enables dual-band modulation with improved visual comfort. The three pyridine-based redox centers facilitate multi-step electron transfer, enabling multi-modal EC regulation, including bright, cool, and dark modes. Incorporation of a fluorinated ionic liquid into EC organogels inhibits irreversible π-stacking of high-concentration H-TriPy. Consequently, H-TriPy-based EC devices achieve neutral-colored states with near-zero transmittance as low as 3.7% in both visible and NIR ranges and maintain high switching stability of over 89.1% retention after 100,000 cycles. Furthermore, large-area EC devices exhibit uniform tinting and reliable stability, underscoring their potential for energy-efficient green buildings.
