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
backgroundOsteosarcopenia is linked to frailty, falls, fractures, and mortality. It may impair intrinsic capacity (IC), with emerging evidence especially pointing to its relationship with cognition capacity. We determined the prevalence and characteristics of persons with possible osteosarcopenia in older adults and examined its association with IC, with a focus on cognition.
methodsTwo thousand, two hundred ninety-one participants were recruited through a national household survey of older adults in Singapore. Socio-demographic, health, and psychosocial variables were collected using questionnaires and physical assessments at baseline. Possible osteosarcopenia was defined by the concurrent presence of possible osteoporosis and possible sarcopenia. Multilevel mixed‑effects regression models examined the association of possible osteosarcopenia with IC at baseline and with cognitive function at 6 months post-baseline.
resultsPossible osteosarcopenia, observed among 50.3% of the cohort, was associated with lower IC at baseline, including cognition capacity. Furthermore, baseline possible osteosarcopenia was associated with poor cognitive function at 6 months post-baseline, particularly among those with loss in cognitive capacity at baseline. This was driven by impaired delayed recall and poor orientation abilities, indicators of both early onset and gradual decline of cognitive impairment. On the other hand, higher education, social networks, resilience, and quality of life were associated with better IC (at baseline) and cognition (at baseline and at 6 months post-baseline).
conclusionsPossible osteosarcopenia is prevalent among older adults in Singapore and is associated with loss in intrinsic capacity and cognitive function, highlighting the importance of early intervention in rapidly aging societies.
