Resilience to psychosocial stress and epigenetic aging in schizophrenia: findings from a pilot study.

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
Exposure to stress is known to affect biological aging as well as individuals' susceptibility to a wide variety of mental illnesses, such as schizophrenia. There is an established relationship between the onset of schizophrenia spectrum disorders (SSD) and biological aging. On the other hand, epigenetic modifications, such as DNA methylation (DNAm), are used as biomarkers for biological aging and were previously proven to be altered in schizophrenia. However, previous research did not consider the effect of psychosocial resilience to stress and its effect on aging in schizophrenia, which is what our study aims to address. For our pilot study, 65 schizophrenia patients were recruited and stress exposure and perception levels were assessed using the Social Readjustment Rating Scale (SRRS) and Perceived Stress Scale (PSS), respectively. Moreover, DNA was extracted from venous blood samples and 850,000 CpG loci were assessed for DNA methylation analysis. Average age of participants was 43.15 ± 13.32 years (55.4% male, 44.6% female). Linear regression plots showed significant correlation between SRRS and PSS scores as well as between biological and chronological ages (p < 0.05). The residuals from the two regression models were defined as the psychosocial resilience and DNAm age acceleration, respectively. Interestingly, DNAm age acceleration was inversely correlated with resilience to stress (p < 0.05). In conclusion, it appears that epigenetic age acceleration is associated with reduced resilience to stress in schizophrenia patients. Future studies should focus on establishing resilience effect on disease prognosis.
