Rare Delayed Ifosfamide Encephalopathy: A Case Report of Chemotherapeutic Neurotoxicity.
Article in Case reports in oncology. 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
Introduction: Neurotoxicity is a well-documented side effect of ifosfamide chemotherapy. The presentation includes hallucinations, seizures, disorientation, coma, and death. Treatment with methylene blue can shorten the duration and severity of symptoms. Ifosfamide neurotoxicity almost always happens during or shortly after drug infusion and so is usually immediately recognized. Here, we describe a case of ifosfamide neurotoxicity with onset 14 days after treatment started. Case Presentation: A 25-year-old woman with round cell sarcoma of the jaw presented to the emergency department with 2 days of encephalopathy and bizarre behavior. Antipsychotic medications and benzodiazepines produced no benefit. After consultation, oncology recommended methylene blue, hypothesizing that her symptoms could be a rare presentation of delayed ifosfamide-induced neurotoxicity, 14 days after first administration. After 4 days of methylene blue infusion, her functioning returned to baseline. Conclusion: Delayed ifosfamide-related neurotoxicity is a rare side effect of this chemotherapeutic agent and should be considered in the workup of altered mental status, even if symptoms occur after the previously accepted 5-day standard. In such patients, delayed symptomology may require extended use of methylene blue as treatment.
