Associations between anxiety, somatic pain and sleep disturbances in major depressive disorder and chronic pain: A cross-sectional study with gender-specific insights.
Article in General psychiatry, 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
Background: Major depressive disorder (MDD) and chronic pain (CP) demonstrate marked sex disparities, with higher prevalence and severity in females. However, the underlying mechanisms remain poorly understood. Aims: We aimed to examine the intricate interplay among anxiety, physical pain and sleep disruptions in inpatients with depression and chronic pain, specifically addressing potential gender differences. Methods: This cross-sectional study enrolled 122 participants and split them into three groups: the comorbidity group (inpatients with MDD and CP, Results: The comorbidity group exhibited greater impairments in pain intensity, anxiety and depressive symptoms, and quality of life compared to other groups. Piecewise regression analysis revealed a nonlinear relationship between the somatic anxiety subscore and pain intensity, with female inpatients in the comorbidity group experiencing higher pain intensity and anxiety severity compared to those in the MDD group. The GAM results showed a peak in pain intensity at a moderate-low threshold in the MDD and comorbidity groups, suggesting an optimal clinical breakpoint (8 points on the somatic anxiety subscore of Hamilton Anxiety Rating Scale-14) for targeted interventions in females. Conclusions: Our findings offer novel insights into the sex-specific dynamics linking anxiety, somatic pain and sleep disturbances in MDD-CP comorbidity, providing an empirical foundation for personalised therapy.
