Work Ability and Work Participation Statuses of the Working-Age Population in Finland: A Register-Based Clustering Study.
Article in Journal of occupational rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeWork ability is a complex concept without a single golden standard measure. This study explores the possibility to use register data to form distinct work ability clusters and examine the levels of work participation between these clusters, while considering the co-occurrence of factors contributing to work ability within the population.
methodsWe used register data from a 90% sample of the Finnish working-age population in 2021 (ages 20-64, n = 2 920 099) to operationalize work ability based on literature. Employing K-Prototypes clustering, we identified distinct clusters of work ability. In this cross-sectional study, we then examined work participation by assessing the number of months spent in employment, unemployment, and receiving disability benefits within each cluster.
resultsThe analysis resulted in 11 distinct clusters. The clusters differed from each other in age, sex, educational attainment, occupation, household size and family type, and health. The average number of months spent in different work participation statuses in 2021 varied across these clusters with employment ranging from 7.3 to 11.6 months, unemployment from 0.3 to 2 months, and disability benefits from 0.2 to 2 months per year.
conclusionsOperationalization of the multifaceted concept of work ability using register data resulted in the identification of different clusters within the Finnish working-age population. Differences in various work ability-related variables highlight the complexity of work ability. Notably, the variation in work participation statuses among these clusters underscores the nuanced ways in which these factors interact to influence employment, unemployment, and reliance on disability benefits.
