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
objectivesThere is a growing interest in understanding the long-term impact of employment status on psychological stress. We aimed to explore the association between socioeconomic status and psychological stress over a long-term follow-up period across the COVID-19 pandemic, employing the Kessler 6-Item Psychological Distress Scale (K6).
methodsWe evaluated K6 scores from the 2021 follow-up survey of NIPPON DATA2010 using a self-administered questionnaire. The association between employment status and changes in K6 scores over 11 years was examined. Multiple regression analyses were used to estimate both crude and adjusted differences in K6 score changes across various socioeconomic factors including employment category, annual household income, marital status, and household size. Analyses were stratified by age, gender, and prefectural population size.
resultsThis study included 1532 participants with an average age of 54.9 years. Over 11 years (2010-2021), participants in both gender and age groups showed increases in mean K6 scores (men: 2.79 to 3.06; women: 3.15 to 3.56; <65 years: 3.27 to 3.47; ≥65 years: 2.37 to 3.08). Nonemployed participants, particularly homemakers, showed significantly greater increases in K6 scores, compared with full-time employees, especially among women, younger individuals, and those in densely populated areas, with a significant interaction with age.
conclusionsNonemployed individuals, especially homemakers, experienced greater psychological stress over the past 11 years than did their fully employed counterparts. Public interventions, including strengthened social connections and telemental health services, may help mitigate these disparities, enhance mental well-being, and foster a sense of belonging.
