Rate of Autoimmune Encephalitis in Children With First-Episode Psychosis.
Article in Pediatric neurology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAutoimmune encephalitis (AE) can present as first-episode psychosis (FEP) in children. An FEP diagnostic algorithm has been proposed, but how this algorithm applies to children is unknown. We assess the FEP diagnostic algorithm in children with FEP.
methodsThe FEP algorithm was applied to a retrospective cohort of children with FEP without other neurological symptoms.
resultsTwenty-four patients were included, with five AE (anti-N-methyl-d-aspartate receptor encephalitis) and 19 non-AE patients (12 primary psychiatric, two headaches, mycoplasma-related encephalitis, post-coronavirus disease 2019 encephalitis, drug reaction with eosinophilia and systemic symptoms [DRESS] syndrome, cobalamin C deficiency, and two unknown). Some non-AE patients (five of 19 = 26%) received immunotherapies, with symptom resolution in one of five (20%) with immunotherapy and in four of 14 (29%) without immunotherapy. The FEP algorithm recommended cerebrospinal fluid (CSF) testing in all (five of five = 100%) patients with AE and in six of 19 (32%) non-AE patients, resulting in 100% sensitivity (95% confidence interval [CI]: 100% to 100%) and 45.5% specificity (95% CI: 16% to 75%), with a negative predictive value of 100% (95% CI: 100% to 100%).
conclusionsFEP can occur in children from different causes, including AE and metabolic conditions. Evaluation of FEP should be broad, especially without CSF evidence of inflammation. The FEP algorithm is useful to assess patients who would benefit from CSF testing and should be assessed in larger cohorts.
