Evaluation of the performance and safety of adding the iron chelator MEX-CD1 to dialysate during continuous veno-venous haemodialysis for removing excess labile iron in intensive care patients with sepsis-associated acute kidney injury - the Iron in Intensive Care trial (
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07236463 (Performance and Safety of Labile Iron Removal by Adding the Iron Chelator MEX-CD1 to Dialysate During Continuous Veno-venous Hemodialysis for Sepsis-associated AKI), which is not on this map.

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.

Abstract
introductionSepsis-associated acute kidney injury is common in intensive care and is linked to high morbidity and mortality, yet no specific therapy exists beyond supportive care. Excess circulating labile iron contributes to oxidative stress, mitochondrial dysfunction and cell death via ferroptosis. We hypothesise that targeted removal of labile iron during dialysis may reduce this pathogenic process. This study will evaluate the performance and safety of adding a novel iron chelator named MEX-CD1 (Metal EXtraction - Chitosan DOTAGA 1) to dialysate during continuous veno-venous haemodialysis (CVVHD) in critically ill patients with sepsis-associated acute kidney injury. METHODS AND ANALYSIS: This is a single-centre, randomised, open-label, crossover phase I-II pilot study in the intensive care unit of Nîmes University Hospital, France. 14 adult patients with sepsis-associated acute kidney injury requiring renal replacement therapy will receive two consecutive 24-hour CVVHD sessions: one with standard dialysate and one with dialysate supplemented with MEX-CD1 at 50 mg/L. Each patient serves as their own control. The primary outcome is the iron concentration in the effluent to measure iron removal performance. Secondary outcomes include plasma iron clearance, trace element loss, biomarkers of oxidative stress and inflammation, and safety outcomes monitored up to 28 days. Statistical analyses will use paired tests and mixed linear regression models. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Comité de Protection des Personnes (no. 25.01220.000448) and the French National Agency for Safety of Drugs and Medical Devices (no. 2024-A01530-47). Results will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT07236463.
