Incidental Changes in Urinary Lead Excretion Following Intra-Venous Ca-DTPA Administration in Patients Treated Primarily for Gadolinium Exposure.
Article in Journal of xenobiotics, 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
Lead is a prevalent environmental pollutant and the heavy metal most frequently associated with toxic effects in humans. This study aimed to evaluate changes in urinary lead excretion following intravenous Ca-DTPA administration. We retrospectively included all patients treated at a medical clinic between January 2023 and March 2025 for suspected symptoms associated with gadolinium exposure who underwent intravenous Ca-DTPA chelation and had both pre- and post-chelation 24 h urine testing for 20 heavy metals. Urinary lead excretion was summarized using mean, standard deviation, median, and interquartile range, and non-parametric testing was applied because values were not normally distributed. A total of 63 participants were included, of whom 37 were female, with a mean age of 48.6 ± 12.5 years, ranging from 15 to 78 years. Median urinary lead excretion increased from 0.283 µg/24 h (IQR, 0.183-0.421) before treatment to 3.22 µg/24 h (IQR, 1.87-5.28) afterward (
