2,4-dinitrophenol intoxication: Lack of adsorption despite prior literature suggesting efficacy.
Article in Toxicology reports, 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
2,4-Dinitrophenol (DNP) is a potent mitochondrial uncoupler associated with life-threatening hypermetabolism and refractory hyperthermia. It remains widely available online despite repeated regulatory warnings and numerous reported fatalities. We report a severe DNP intoxication with multi-organ dysfunction in a 22-year-old man. Continuous veno-venous hemodialysis combined with CytoSorb® hemoadsorption (HA) was initiated as previous reports suggest a benefit associated with these techniques. Serial measurements were performed to assess extracorporeal clearance, which was calculated using pre- and post-adsorber blood sampling. No meaningful reduction in plasma concentration or adsorber-based clearance was observed, indicating minimal extracorporeal elimination of DNP. The patient improved under supportive care including active cooling and recovered fully. This case highlights that declining serum concentration alone are not sufficient to evaluate effectiveness of HA for toxin removal and emphasize the importance to use EXTRIP dialyzability criteria. Overall, HA with CytoSorb® demonstrated no measurable DNP elimination.
