The First Seasonal Green View Index Mapping Dataset across Chinese cities powered by deep learning.
Article in Scientific data, 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
Multi-temporal mapping of the Green View Index (GVI) is crucial for understanding how urban residents perceive seasonal changes in streetscape greenness. Compared to street view imagery (SVI), remote sensing data offers higher temporal frequency and broader spatial coverage, enabling large-scale dynamic monitoring. However, most existing GVI estimation methods rely heavily on SVI, limiting their ability to support cross-city and seasonal analysis. To address this gap, we present the Seasonal Green View Index 2023 (SGVI-2023), a GVI mapping dataset derived from multisource remote sensing data and deep learning. Covering 19 major Chinese cities, SGVI-2023 was developed using approximately 1 million paired samples of satellite and SVI data collected from 2019 to 2023. All data underwent strict preprocessing and partitioning. Evaluation results show strong accuracy, with Pearson correlations of 0.867 at the point scale and 0.918 at the street scale. As the first cross-city, seasonally resolved GVI dataset based on remote sensing, SGVI-2023 provides valuable support for human-centered urban greenness monitoring and data-driven urban planning.
