Apathy in patients with Neuromyelitis Optica Spectrum Disorder.
Article in PloS one, 2025. 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
backgroundApathy is a common neuropsychiatric complication of neurological diseases, but it has not been investigated in patients with neuromyelitis optica spectrum disorders (NMOSD) until now.
methodsWe enrolled 66 patients diagnosed with NMOSD and assessed apathy using the self-reported version of the Apathy Evaluation Scale (AES-S). All the patients also completed the investigations composed of demographic data, disease characteristics, and composite evaluations of life status, including anxiety/depression, fatigue, sleep, and quality of life. Further statistical analysis proceeded.
resultsThe mean AES-S score was 36.7 ± 8.3, with 40.9% of patients exhibiting clinically significant apathy (cutoff score: 36). Correlation analysis revealed that higher AES-S scores were significantly correlated with lower education attainment (p = 0.002), more number of attacks (p = 0.008), longer disease duration (p = 0.004), higher disability (p = 0.03), severer anxiety (p < 0.001), severer depression (p < 0.001), severer fatigue (p < 0.001), and severer sleep disturbances (p = 0.001). Depression was revealed to be a significant independent factor of apathy (P < 0.001). The subscales of AES-S and its correlated factors were also analyzed. Further analysis showed that the AES-S score was negatively correlated with the total score of the quality of life scale and all the sub-dimensions' scores (P < 0.05).
conclusionsThese results suggest that apathy is a common neuropsychiatric complication in patients with NMOSD and is closely related to their quality of life. The apathy of NMOSD correlated with various physiological and psychological changes, especially depression. These findings might help us identify patients with a high risk of apathy, highlighting the importance of evaluating and managing apathy is of great significance for improving the quality of life in NMOSD patients.
