Heavy Metal Analysis of Commercial Rice Grains from Varanasi City of India: Insight into Contamination Level, Daily Intake and Associated Health Risks.
Article in Biological trace element research, 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
Rice (Oryza sativa L.) is a staple food in Many Asian countries and plays a vital role in global food security. Heavy metal contamination of the rice grains is a global concern, yet data on contamination level and associated risks in Northern India remain Limited. Thus, the present study quantified concentrations of Cd, Cr, Pb, As, Ni, Cu, and Zn in 19 rice grain varieties consumed by urban population of India using an Atomic Absorption Spectrophotometer. Hazardous risks of consuming rice grains were assessed through computing estimated daily intake (EDI), target hazard quotient (THQ), and target cancer risk (TCR). Results showed that Pb, As, and Ni levels in rice grains were below the detection thresholds (0.2, 0.2, and 0.04 µg g⁻
