Work productivity by diseases diagnosed among workers: a study using large-scale claims data and survey data of workers in Japan.
Article in Journal of occupational health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesJapan faces the need for occupational health management based on an understanding of workers' health and its impact on work productivity. Given a paucity of comprehensive studies, we conducted this study to investigate work productivity by diseases among workers of various occupations in Japan, by using a large-scale database.
methodsThis retrospective, descriptive study used pre-existing data derived from health insurance claims and 2 surveys conducted in 2021. The analysis included the data of ≥19-year-old current workers with response data to the questions regarding Work Productivity and Activity Impairment (WPAI). The WPAI of the target diseases, defined by claims diagnosis codes, was plotted against the 1-year prevalence of each disease. The cost of lost productivity was estimated based on the response data regarding the WPAI.
resultsOverall, 31 540 individuals participated, and the analysis showed that psychiatric disorders, headache, epilepsy, and insomnia had a high percentage of participants reporting any level of WPAI, although the prevalence of these diseases was low. We also explored the cost of lost productivity to supplement the interpretation of the overall impact of health problems; however, no clear trend was observed.
conclusionsMany Japanese workers with psychiatric disorders, headaches, epilepsy, and insomnia have impaired work productivity and daily activities.
