The Association of Sleeping Duration and Sleep Problems With All-Cause Mortality Among a Cohort of Industrial Workers Followed Up for 36 Years.
Article in American journal of industrial medicine, 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
backgroundSleep duration is a well-established factor associated with all-cause mortality and cardiovascular mortality. Poor sleep quality was also suggested to affect all-cause mortality risk among adults. The Cardiovascular Occupational Risk Factor determination in Israel Study (CORDIS) is a prospective cohort study of industrial workers who entered the study during 1985-1990 and have been followed for 36 years. We examined the relationship between sleep duration, sleeping problems and difficulties, and all-cause mortality in the CORDIS cohort.
methodSelf-reported data, including sleep duration and sleeping problems, from 7287 participants were merged with data on all-cause mortality obtained from the National Death Registry and the Central Bureau of Statistics.
resultsOver the 36-year follow-up, 2159 participants died: 445 were < 45 years and 1714 were ≥ 45 years. Sleep duration of ≤ 5 h significantly increased mortality risk (hazard ratio [HR] = 1.30, p = 0.0032), with a more pronounced effect in those < 45 years (HR = 1.55, p = 0.0028). Sleeping problems also increased mortality risk (HR = 1.30, p = 0.0088), with a stronger association among younger individuals (HR = 1.63, p = 0.0399). Conversely, difficulty sleeping when anticipating something unpleasant was linked to increased mortality only in those aged ≥ 45 years (HR = 1.17, p = 0.0440).
conclusionsOur analysis showed that short sleep duration and sleeping problems are significant predictors for all-cause mortality, particularly in younger individuals (< 45 years). These results emphasize the importance of addressing sleep problems among different age groups to potentially reduce mortality risk.
