Severe efavirenz associated neurotoxicity: A retrospective cohort study.
Article in Southern African journal of infectious diseases, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Efavirenz (EFV) is associated with neuropsychiatric symptoms. Severe neurotoxicity has been reported but the clinical phenotype and risk factors are poorly defined. Objectives: To characterise clinical presentations, risk factors and outcomes to help clinicians recognise severe neurotoxicity earlier. Method: The authors retrospectively identified adults with supratherapeutic EFV concentrations (> 4 mg/L) obtained during routine clinical care in Cape Town, South Africa. Clinical and laboratory data at the time of EFV quantification were extracted from medical records. Logistic regression was performed to identify associations with neuropsychiatric symptoms, and with severe neurotoxicity. Results: Eighty one patients were included; 62 with neuropsychiatric manifestations (most frequently ataxia [ Conclusion: A concentration-effect relationship for severe neurotoxicity exists, which occurred late and resolved in most patients after EFV discontinuation. Contribution: The authors highlighted clinical heterogeneity and morbidity of EFV-associated neurotoxicity.
