Moderating role of supervisor support in the association between job demands and distress: a mixed-effects analysis in a population-based cohort study.
Article in BMJ open, 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
objectivesTo study the association between job demands and distress among working adults and to test whether perceived supervisor support moderates this relationship.
designMixed-effects analysis of repeated measures from a population-based cohort study, estimating overall (combined within-person and between-person) associations.
settingThe Netherlands Longitudinal Study on Hearing (NL-SH), an ongoing Dutch cohort with nationwide recruitment and follow-up including four measurement waves.
participantsA total of 989 employed individuals (≥12 hours/week) with 1858 observations had complete data on distress, job demands, supervisor support and covariates. PRIMARY AND SECONDARY OUTCOME MEASURES: The dependent variable was distress, measured using the 16-item distress subscale (range 0-32) of the Four-Dimensional Symptom Questionnaire. Job demands and supervisor support were assessed with subscales from the Job Content Questionnaire. Multilevel linear models were used to estimate main and interaction effects, adjusted for age, sex, educational level, hearing impairment, contract type and chronic diseases.
resultsHigher job demands were associated with greater distress (B=0.22, 95% CI (0.17 to 0.27)). Higher supervisor support was associated with lower distress (B=-0.26, 95% CI (-0.38 to -0.15)). The interaction between job demands and supervisor support was statistically significant (B=-0.02, 95% CI (-0.04 to 0.001), p=0.042). Stratified analyses showed that the association between job demands and distress was stronger among employees with low supervisor support (B=0.27, p<0.001) than among those with high support (B=0.13, p=0.008).
conclusionsJob demands and supervisor support were independently associated with distress. Supervisor support appeared to buffer the impact of job demands, as the association between job demands and distress was stronger among employees reporting low levels of supervisor support. These findings underscore the importance of strengthening supportive supervisor practices, alongside addressing excessive job demands, as integral components of workplace mental health strategies.
