1 · What the graph read from 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.

2 · The registry

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

Introduction: Both on-duty and off-duty internet use are increasing and may have health effects. Off-duty internet use, in particular, has increased rapidly due to the proliferation of smartphones. This study aimed to clarify the relationship between prolonged off-duty internet use and depression among Japanese civil servants. Methods: A cross-sectional survey was conducted in 2019 among 3,751 civil servants aged 20-65 years employed by a local government on the west coast of Japan. Psychosocial stress at work, work-family conflict, and time spent using the internet were evaluated. Logistic regression analysis was performed to examine whether there is an association between off-duty internet use time and depression as measured using the Japanese version of the Center for Epidemiologic Studies Depression Scale. Results: The study included 3,403 participants; depressive symptoms were present in 28.3% (26.1% of men and 31.4% of women). Multivariate analysis showed that, in women, prolonged off-duty internet use, low job control, low job support, being unmarried, work-family conflict, and low sleep quality were associated with depression. In men, in addition to these factors, low job class, no overtime work, high job demands, chronic illness, and sleep duration were associated with depression. While multivariate analysis revealed no statistically significant association between electronic device use at work and depression, prolonged off-duty internet use (≥4 hours per day) was significantly associated with higher odds of depression in both men (odds ratio [OR] 1.83, 95% confidence interval [CI] 1.08-3.10) and women (OR 2.31, 95% CI 1.32-4.05). Conclusions: Prolonged off-duty internet use was independently associated with depression among Japanese civil servants. This association may be related to factors such as superficial virtual connections or information overload. More attention should be paid to internet use for maintaining the mental health of civil servants.
