Association between sense of coherence and loss of independence or death in older adults: Locomotive Syndrome and Health Outcomes in Aizu Cohort Study.
Article in PloS one, 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
backgroundAlthough sense of coherence (SOC) is a core concept to promote healthy aging, evidence of whether SOC improves loss of independence (LOI) or death is lacking. We aimed to investigate the association between SOC and LOI or death in older adults.
methodsWe enrolled independent older adults aged 65 years or over from a population-based cohort. SOC was assessed using a three-item SOC scale at baseline. The primary outcome was a composite of LOI (defined by Japanese long-term care insurance certification) or death. We investigated the association of SOC with LOI or death using the Cox proportional hazards model.
resultsDuring a median follow-up of 5.8 years, 128 out of 1,661 (7.7%) participants had LOI or death. Lower SOC (per 1 standard deviation [SD] decrease) was associated with a higher risk of LOI or death (adjusted hazard ratio 1.25, 95% confidence interval [CI] 1.07 to 1.46, p = 0.005). Lower SOC (per 1 SD decrease) was associated with a higher risk of death (adjusted hazard ratio 1.24, 95% CI 1.03 to 1.50, p = 0.022) as well.
conclusionsOlder adults with a lower SOC were more likely to experience LOI or death. Enhancing SOC could promote healthy aging in older adults.
