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
Background: Carbamazepine (CBX) is widely used for various medical conditions, but its associated toxicity poses significant clinical concerns. This study aims to provide insights into the clinical presentations, management strategies, and outcomes of CBX toxicity cases in an emergency department (ED) setting. Methodology: This was a 10-year retrospective cohort chart review study, including all patients with elevated CBX levels. Data on clinical features, CBX levels, laboratory findings, electrocardiograms (ECGs), patient management, and outcomes were analyzed. Cases were categorized as acute or chronic toxicity. Results: Out of the 1,965 medical charts reviewed, we included 70 patients with CBX levels above the therapeutic range (prevalence: 3.6%). Chronic CBX toxicity cases (55.7%) were predominant, with gastrointestinal (GI) symptoms being the most common. Most patients presented with isolated CBX overdoses (88.6%), while mixed overdoses (11.4%) were less frequent. Patients were categorized based on CBX levels: 44 had mild toxicity (>51 μmol/L), and 26 had moderate toxicity (>85 μmol/L). Within the mild group, 15 patients experienced acute toxicity, compared to 16 patients in the moderate group. Four patients who had mixed overdoses and low sensorium required intubation and mechanical ventilation. Three patients received activated charcoal (AC), and another 3 patients received multiple doses of AC to reduce drug absorption. The majority of patients (65.7%) required hospital admission, underscoring the seriousness of CBX toxicity. There were no fatalities among these 70 patients. Conclusion: This study emphasizes the importance of a systematic approach to assessing and managing CBX toxicity, considering its diverse clinical presentations and variations in serum CBX levels.
