Daily presenteeism fluctuates substantially among Japanese workers while converging with retrospective WHO-HPQ scores.
Observational study in Journal of occupational health, 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
objectivesPresenteeism is commonly assessed using retrospective instruments such as the World Health Organization Health and Work Performance Questionnaire (WHO-HPQ); however, how daily presenteeism assessed using experience sampling relates to these standard measures remains unclear. This study quantified within-person variability in daily presenteeism assessed using experience sampling methods (ESMs) among Japanese workers, while also examining its convergence with retrospective WHO-HPQ presenteeism.
methodsThis observational study enrolled 94 white-collar employees; 93 were included in the final analysis after exclusion of 1 participant because of missing data. Participants completed daily work performance assessments on 19 weekdays using a mobile-based ESM approach. Aggregated daily presenteeism scores were compared with retrospective WHO-HPQ presenteeism scores assessed over the preceding 4 weeks. Convergence was evaluated using Spearman rank correlation coefficient, and agreement was examined using Bland-Altman analysis. Within-person variability was quantified using the coefficient of variation (CV) and intraclass correlation coefficient (ICC).
resultsMean daily absolute presenteeism scores were strongly correlated with retrospective WHO-HPQ presenteeism scores (Spearman rs = 0.783, P < .001). Bland-Altman analysis showed minimal systematic differences on average, despite substantial individual-level variability. Daily presenteeism exhibited substantial variability, with a CV of 42.2% (95% CI, 36.7-47.6) and an ICC of 0.431.
conclusionsDaily presenteeism converged with retrospective WHO-HPQ presenteeism while capturing substantial within-person variability that is not fully reflected in retrospective assessments. These findings support interpreting presenteeism as a dynamically fluctuating state and highlight the importance of selecting measures with appropriate temporal resolution.
