Work disability status following routine mental health treatment: a Norwegian registry-based cohort study.
Article in BMC health services research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
objectivesSickness absence due to mental disorders is increasing in many high-income countries, yet the impact of routine mental health treatment on work disability outcomes remains unclear. This study examined trajectories of work disability (working, partly or full sick leave, Work Assessment Allowance, or disability pension) before and after routine mental health care and identified factors associated with work disability status.
methodsA prospective cohort of 2,609 adult outpatients with mild to severe mental disorders receiving routine mental health treatment in Norwegian community or specialist services was followed. Registry data tracked work disability status one year before and after treatment. Group-based trajectory modelling, sequence clustering, and multinomial logistic regression were used.
resultsWork disability increased sharply in the year prior to treatment, peaking at 38% at treatment start. Although a modest decline in absenteeism followed, long-term medical benefits of Work Assessment Allowance steadily rose from 7% pre-treatment to 18% post, a 152% increase, contributing to sustained levels of absenteeism after start of treatment. Five trajectories were identified, with 46% maintaining stable work ability. Approximately 30% of patients, corresponding to clusters 3 and 4, experienced reduced sick leave with benefit transition to long-term medical benefits, while 7% were permanently on disability pension. Older age, female sex, and treatment in specialist services were associated with higher work disability, while community services targeting mild to moderate conditions were linked to better work ability outcomes.
conclusionsWork disability increased sharply before treatment and remained persistently high throughout the following year, forming a plateau across care levels. Although nearly half of the patients maintained stable work ability, the findings indicate that routine mental health care, especially specialist services, may have limited effectiveness in preventing long-term work disability. A substantial proportion transitioned into long-term medical benefits, highlighting the urgent need for timely interventions that integrate work ability as a core treatment objective and apply targeted interventions to enhance it.
