Herpetic encephalitis: which treatment for which body weight?
Article in Journal of neurology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundPrognosis of herpetic encephalitis remains severe, with a high proportion of deaths and sequelae. Its treatment is based on acyclovir, but the precise and most effective modalities of this treatment are not established. The objective of this study was to determine them.
methodsFor this, we carried out a descriptive, retrospective, monocentric study, using the current coding database at Marseille University Hospitals. Cohort was intended to be exhaustive for the disease, from January 2000 to June 2019, including patients hospitalized in intensive care and conventional hospitalization sector. Patients (n = 76) included were at least 16 years of age and had a clinical presentation, cerebral Magnetic Resonance Imaging, and/or electroencephalogram abnormalities consistent with herpetic encephalitis confirmed by a positive HSV-PCR in the CSF. Clinical data and treatment, including the doses actually administered to the patient, were compared according to patient's outcome.
resultsThe mortality rate was 12%, whereas 49% had complete recovery and 39% sequelae impeding independence. Poor outcome was statistically associated with persistence of confusion, aphasia, and impaired consciousness lasting more than 5 days, superinfection, status epilepticus, and length of stay in intensive care unit. A statistical decision tree, constructed using the Classification And Regression Tree model, to prioritize treatment management, showed two main factors that influence the outcome: the patient's weight, and the average daily acyclovir dose actually administered.
conclusionThese results suggest to modify acyclovir management in herpetic encephalitis, for low-weight patients (< 79 kg) with a minimum dosage of 2550 mg/day (850 mg/ 8 h), when possible.
