Global Trends in Light Pollution and Their Relationship With Socioeconomic Factors.
Article in Annals of the New York Academy of Sciences, 2026. 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
Artificial light at night (ALAN) is a growing environmental pressure linked to socioeconomic development. This study examines ALAN trends from 2012 to 2024 across 165 countries using harmonized VIIRS satellite data. Globally, ALAN increased at an annual rate of 3.2%. Highest radiance levels occur in developed regions (Europe, North America, and East Asia), while remote areas remain dark. A few countries, including France and Venezuela, show declines. The study extends the VIIRS time series and applies a calibrated Kaya-identity framework integrating the human development index (HDI) and Gini coefficient. It introduces radiance density (RD) as a normalized metric linked to per-capita development for cross-national comparison. ALAN shows associations with macroeconomic indicators. Absolute ALAN correlates with total GDP (log), energy consumption, and CO
