D,L-3-hydroxybutyrate in the treatment of glucose transporter 1 deficiency syndrome (Glut1DS).
Article in JIMD reports, 2025. 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: Deficiency of the Glut1 transporter due to mono-allelic variants in Methods: A retrospective case review of patients with Glut1DS under the Adult and Paediatric National Metabolic Service (APNMS) of New Zealand, treated with D,L-3-HB between 2012 and 2023 was performed. Clinical notes, standardised, neuropsychological assessments and subjective data on and off D,L-3-HB were obtained. The best on and off D,L-3-HB measures of working memory (WMI) and processing speed (PSI) were compared to assess the efficacy. Results: D,L-3-HB was offered to 12 patients with Glut1DS (age 10-52 years). Compliance-dependent improvements in subjective, cognitive and adaptive function were reported by those who were reassessed on-treatment (9/12). Four reported improved PMD. Objective improvements were found in WM (9/9) and PS (6/9). Subjective improvements were reported in patients' health, wellbeing and independence. Conclusions: KD remains standard of care for Glut1DS, but effective alternatives are lacking for those who do not tolerate this. D,L-3-HB was associated with improved WM, PS and perceived life quality in this small group of patients with Glut1DS, thus providing a potential treatment for this distinct group.
