Assessment of Heavy Metal Contamination, Distribution, and Source Identification in Surface Sediments from the Mid-Upper Reaches of the Yellow River.

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
River sediments serve as both a source and a reservoir for potential heavy metal pollutants, providing critical insights into the health of aquatic ecosystems. Heavy metal contamination in global river systems poses significant risks to human health through the food chain. This study investigates the contents of heavy metals, including Fe, Mn, Cu, Ni, Zn, Cr, Pb, and Cd, in surface sediment samples collected from the mid-upper reaches of the Yellow River, which flows through the provinces of Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, and Henan. We analyzed the contents and spatial distribution characteristics of these metals and assessed their pollution levels by identifying potential sources of contamination. The findings reveal elevated concentrations of Cr and Cd in the mid-upper reaches of the Yellow River, with particularly severe pollution observed in certain urban areas. The sources of these heavy metals are primarily linked to human activities related to production and daily life. This study offers valuable guidance for local pollution control and prevention strategies.
