N-methyl-D-aspartate receptor autoantibody levels in children with intractable and non-intractable epilepsy.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Intractable epilepsy in children is a prevalent neurological disorder that can pose serious risks. The involvement of the autoimmune system is a significant factor in the pathogenesis of the disease. The N-methyl-D-aspartate-receptor (NMDAR) is a glutamate receptor and ion channel present in neurons and is associated with the mechanism of autoimmune etiology in epilepsy. This study aims to compare the levels of NMDAR auto antibodies in children with intractable and non-intractable epilepsy. Methods: A prospective analytic study was conducted from June to September 2022. The study sample consisted of patients aged 1 month to 18 years diagnosed with epilepsy and receiving anti-seizure medication (ASM) therapy at Dr. Soetomo General Academic Hospital, Surabaya. The patients were divided into two groups, namely intractable epilepsy and non-intractable epilepsy. The NMDAR autoantibody levels were determined using enzyme-linked immunosorbent assay (ELISA). Statistical analysis employed the chi-squared and Wilcoxon-Mann-Whitney tests. Results: Seventy-five subjects were included in the study. Of these patients, 41.3 % with intractable epilepsy and 33.4 % with non-intractable epilepsy presented NMDAR auto antibodies. Analysis of the patient characteristics revealed a correlation between seizure frequency and NMDAR autoantibody positivity (P = 0.002) but not between the number of ASM and NMDAR autoantibody positivity (P > 0.05). The NMDAR autoantibody levels were not significantly different in children with intractable and non-intractable epilepsy (P = 0.157). Conclusion: The NMDAR autoantibody levels were numerically higher in children with intractable epilepsy compared with children with non-intractable epilepsy.
