Incidence and Prognostic Implications of Mental Disorders Among Patients With a Permanent Pacemaker: A Nationwide Cohort Study.
Article in Journal of the American Heart Association, 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
backgroundThe burden of mental disorders among patients with permanent pacemakers (PPMs) and their impact on long-term outcomes remain poorly understood. We aimed to investigate the incidence of newly diagnosed mental disorders among PPM patients and to evaluate their prognostic implications.
methodsFrom the Korean National Health Insurance Service database, we identified 19 746 patients who underwent PPM implantation and 58 642 propensity score-matched controls without a PPM between 2010 and 2020. Among PPM patients, long-term clinical outcomes were compared according to the presence of newly diagnosed mental disorders.
resultsThe 10-year cumulative incidence of any newly diagnosed mental disorders among PPM patients was 45.1%. The most common mental disorders were depressive disorder (24.6%), insomnia (20.6%), and anxiety disorder (5.6%). The overall risk of detecting new mental disorders among PPM patients was similar to that of the matched general population (hazard ratio [HR], 0.98 [95% CI, 0.96-1.01]). However, male PPM patients showed a significantly higher risk, particularly those aged <50 years (HR, 1.42 [95% CI, 1.16-1.75]) and those aged 50 to 59 years (HR, 1.20 [95% CI, 1.04-1.38]). PPM patients diagnosed with any mental disorder had a significantly higher 10-year cumulative all-cause mortality compared with those without mental disorders (53.6% versus 31.3%; HR, 1.71 [95% CI, 1.61-1.82]), with the highest risk observed in patients with schizophrenia (HR, 3.23 [95% CI, 2.61-4.00]). Adverse outcomes were more pronounced in male patients and when mental disorders were diagnosed early after implantation (within 3.2 years).
conclusionsAlthough the risk of detecting new mental disorders among PPM patients was comparable to that of the matched non-PPM population, newly diagnosed mental disorders were associated with increased long-term mortality in PPM patients, particularly in younger men and those with early-onset mental disorders.
