A Global Imprint of Gadolinium-Based Contrast Agents Used in Magnetic Resonance Imaging in Drinking Water.
Article in Environmental science & technology, 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
Since the 1980s, rare earth elements (REE), particularly gadolinium (Gd) used in gadolinium-based contrast agents (GdCA), have revolutionized Magnetic Resonance Imaging (MRI) diagnostics. However, the near-complete persistence of these compounds through wastewater treatment processes has led to widespread global environmental contamination. Here, we present a global assessment of REE concentrations and GdCA signatures in tap water from 148 cities across 89 countries and Antarctica, where anthropogenic Gd ranges from 0.1 to 61.2 ng L
