Radionuclides in Milk: A Global Systematic Review and Meta-Analysis and Probabilistic Human Risk Assessment.
Review in Food science & nutrition, 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
This study conducted a systematic review and meta-analysis of radionuclide concentrations of Cesium-137 (Cs-137), Cesium-134 (Cs-134), Iodine-131 (I-131), Lead-210 (Pb-210), and Potassium-40 (K-40) in milk worldwide, along with an assessment of human health risks, in accordance with the PRISMA guidelines. Pooled radionuclide concentrations were estimated using a random-effects model, while excess lifetime cancer risk (ELCR) was calculated to evaluate carcinogenic effects using the Monte Carlo Simulation (MCS) model. A comprehensive search of Scopus, PubMed, Embase, and Web of Science identified 66 papers (200 data reports, 2000-2025) that cover milk samples from 32 countries. The global pooled mean concentrations (Bq/L) followed the order: K-40: 57.494 > Cs-137: 0.904 > I-131: 0.301 > Pb-210: 0.136 > Cs-134: 0.032. Extreme concentrations were observed in the United Kingdom (Cs-137: 288.000), Syria (I-131: 76.000; K-40: 243.500), and India (Pb-210: 1.080), whereas Mali (Cs-137: 0.003) and Algeria (K-40: 2.349) showed the lowest levels. Probabilistic human health risk assessments revealed that the mean cancer risk (CR) for adults from Cs-137 ingestion exceeded the acceptable limit (1E-4) in the United Kingdom, Austria, South Korea, Serbia, the Czech Republic, Germany, Kazakhstan, and Iceland. For Cs-134, the CR in Finland and France remained below the limit. The CR from K-40 exceeded the limit in Spain, Syria, Bangladesh, Mali, Iraq, Singapore, Thailand, Japan, Italy, and Turkey. For I-131, the limit was exceeded in Syria, Romania, Greece, and Spain. The CR of Pb-210 exceeded the limit in Tunisia, Slovenia, India, the Czech Republic, Italy, and Syria. These disparities reflect variations in environmental contamination, nuclear legacy, and regulatory standards. The results highlight the necessity for strict monitoring, especially in high-risk areas, and promote enhanced agricultural practices and food safety policies to reduce radionuclide exposure through milk consumption.
