The association between speech impairments and depression in Chinese adults aged 45 and older: insights from the CHARLS database.
Article in BMC psychiatry, 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
backgroundSpeech impairments significantly affect communication and are associated with social and psychological difficulties, particularly among adults aged 45 years and older. This study examines the relationship between speech impairments and depression using data from the China Health and Retirement Longitudinal Study (CHARLS).
methodsA total of 67,014 participants aged 45 years and older were included in the analysis. The baseline characteristics of participants with and without speech impairments were compared using chi-square tests. Multivariable logistic and linear regression models were employed to assess the association between speech impairments and depression. Sensitivity and subgroup analyses were performed to explore variations across different demographic and lifestyle characteristics.
resultsParticipants with speech impairments exhibited a significantly greater likelihood of depression, with adjusted odds ratios (Model II: OR = 2.16, 95% CI: 1.56-2.97, p < 0.0001) and higher depression scores (Model II: β = 3.03, 95% CI: 2.24-3.81, p < 0.0001) after controlling for confounders. Sensitivity analysis confirmed the robustness of these findings. Subgroup analysis revealed consistent associations across all the examined subgroups, with a statistically significant interaction between speech impairments and place of residence (p for interaction = 0.02), indicating a stronger association in urban residents.
conclusionSpeech impairments are strongly associated with a greater likelihood of depression in middle-aged and elderly Chinese adults. This finding underscores the importance of targeted mental health interventions and support for this population, particularly in urban settings. CLINICAL TRIAL NUMBER: Not applicable.
