Lead poisoning in a 10-year-old boy with cyclic vomiting as the first symptom: a case report.

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: Lead is a naturally occurring metal with highly toxic effects on humans, particularly children, who are particularly vulnerable to its long-lasting adverse impacts. Patient concerns: This report presents the case of a 10-year-old boy with a 10-month history of recurrent vomiting. No organic lesions were identified. However, the symptoms were inconsistent with cyclic vomiting syndrome (CVS), given the presence of growth retardation, vitamin D deficiency, bilateral cervical lymphadenopathy, academic difficulties, and impaired concentration. Diagnosis: Detailed history-taking revealed proximity to a lead mining facility. Blood lead level (BLL) was significantly elevated (382 μg/L), confirming chronic lead poisoning. Interventions: Chelation therapy with dimercaptosuccinic acid (DMSA) was administered for 19 days at a 350 mg/m Outcomes: Following treatment, BLL decreased to 168 µg/L, accompanied by significant improvement in vomiting and abdominal pain. Conclusion: Pediatric lead poisoning should be considered in the differential diagnosis of children presenting with cyclic vomiting and neurological symptoms, due to its diagnostic complexity.
