A Preliminary Open-Label Pilot Study of a Pillow-Based ELF-ELME (Extremely Low-Frequency, Extremely Low Magnetic Environment) Intervention for Major Depressive Disorder.
Trial report in Neuropsychopharmacology reports, 2026. 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
backgroundMitochondrial dysfunction has been implicated in the pathogenesis of depression. Major depressive disorder (MDD) is a prevalent condition with substantial individual and societal burden. A novel approach-exposure to an extremely low-frequency, extremely low magnetic environment (ELF-ELME)-has shown promise. This preliminary study builds on a previous trial using a head-mounted ELF-ELME device and explores the potential efficacy and safety of a pillow-based ELF-ELME device in patients with MDD.
methodsIn this preliminary open-label pilot study, four patients with MDD were treated using a pillow-based ELF-ELME device (10 μTesla, 4 ms, 1-8 Hz/8 s) for 2 h daily over 8 weeks. The primary outcome was change in Montgomery-Åsberg Depression Rating Scale (MADRS) scores from baseline to Week 8. Artificial Intelligence-based MADRS (AI-MADRS) scores were also assessed.
resultsTotal MADRS scores showed a unidirectional decrease from baseline (33.8 ± 7.3) to Week 8 (21.5 ± 8.7; p = 0.050, FDR = 0.067), and no time point reached statistical significance after FDR correction. In contrast, AI-MADRS scores significantly decreased from baseline (34.0 ± 8.3) to Week 8 (19.8 ± 6.8; p = 0.040). No serious adverse events were reported.
conclusionThese preliminary findings suggest that an 8-week course of pillow-based ELF-ELME intervention may have potential to alleviate depressive symptoms in patients with MDD. However, given the small sample size and open-label design, the results should be interpreted with caution. Larger controlled studies are warranted to confirm these findings.
