Epigenetic aging in anxiety disorders: diagnostic subtype differences and associations with social functioning.
Article in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundAnxiety disorders, including subtypes such as social anxiety disorder (SAD), panic disorder (PD), and generalized anxiety disorder (GAD), are among the most common psychiatric disorders. They are characterized by excessive fear, anxiety, and behavioral disturbances, leading to significant impairments in social and occupational functioning. While both accelerated and suppressed epigenetic aging have been reported in various psychiatric disorders, findings in anxiety disorders remain limited. We investigated diagnostic subtype-specific patterns of epigenetic age acceleration in anxiety disorders and examined the influence of social functioning.
methodsDNA methylation (DNAm) was quantified in 266 healthy individuals and 30 individuals with anxiety disorders (11 SAD, 11 PD, and 8 GAD) using Illumina MethylationEPIC arrays. Epigenetic age acceleration was estimated using PCHannumG2013 as the primary clock, with sensitivity analyses conducted using four additional clocks. Social functioning was assessed with the Social Functioning Scale. Meta-analyses incorporating data from previous DNAm-based studies (423 healthy individuals and 278 individuals with anxiety disorders) were performed.
resultsCompared with healthy individuals, individuals with anxiety disorders had suppressed epigenetic age acceleration, particularly in SAD, in our cohort. Lower social functioning, especially impaired independence-competence and reduced prosocial activities, was associated with suppressed epigenetic age acceleration. Meta-analyses revealed suppressed epigenetic aging in patients with SAD and a marginal increase in patients with PD. Sensitivity analyses revealed that the suppression in SAD was consistently detected across clock types, except for DunedinPACE.
conclusionsOur findings suggest possible diagnostic subtype-specific differences in epigenetic age acceleration in anxiety disorders, which may indicate a potential protective role of social avoidance in patients with SAD and the influence of inflammatory processes in patients with PD.
