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

Understanding population distribution and ethnic composition is essential for formulating effective regional development plans, providing insights into the evolutionary characteristics of populations, unraveling historical human heritage, and fostering cultural integration. The Dehong Autonomous Prefecture in Yunnan Province, China, stands out not only for its concentration of various ethnic minorities but also for its proximity to Myanmar. Utilizing toponymic data, night-time light data, demographic data, and census data, we meticulously visualized the spatial distribution and temporal changes of five indigenous ethnic minority groups (IEG), namely the Dai, Jingpo, Deang, Lisu, and Achang ethnic groups. This comprehensive approach allows us to delve deeper into the distribution index to gain profound insights into each IEG group. We found that Dai and Jingpo ethnic groups are almost ubiquitous throughout the study area, while other IEG exhibit distinct regional distribution characteristics. The existence of multiple minorities in economically developed area shows a phenomenon of cohabitation, and the widespread distribution of Dai and Jingpo ethnic groups facilitates communication and exchanges between different aggregation areas. This study holds immense significance in fostering cross-cultural exchanges, safeguarding and perpetuating minority cultures, promoting the sustainable development of minority communities, and advancing the application of remote sensing through nighttime lights.
