Observations on Intrinsic Capacity and Sarcopenia in Healthcare-Seeking Older Adults.

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
Introduction Sarcopenia is a generalized disorder of skeletal muscle associated with adverse outcomes in older adults. With advancing age, the ability to overcome adverse outcomes reduces as measured by reduced intrinsic capacity (IC). Therein lies an underlying pathophysiological relationship between sarcopenia and IC. Our study aimed to explore the association between IC and sarcopenia in healthcare-seeking older adults in India. Materials and methods We conducted a cross-sectional study at a tertiary care hospital in New Delhi, India. One hundred and thirty older adults (90 men and 40 women) aged 65 years attended outpatient department services. Sarcopenia was diagnosed as per the Asian Working Group for Sarcopenia (AWGS) 2019 consensus criteria. IC was evaluated as the sum of five domains defined by the World Health Organization (WHO), namely, cognition, sensory (self-reported vision and hearing), locomotion, vitality (nutrition), and psychological. The IC composite score was calculated by summing of scores of all five domains, with a higher score representing lower IC. Results The mean age of patients was 70.8±5.8 years. Twenty-six patients (20%) had sarcopenia. Sarcopenic patients were older, less physically active, had a similar incidence of chronic comorbidities, and had significant polypharmacy as compared to non-sarcopenic patients; 73% of total patients had impairment in at least one domain of IC. Cognition, locomotion, sensory, vitality, and psychological domains were impaired in 26%, 48%, 65%, 52% and 44% of total patients, respectively. The median IC composite score was 2 in non-sarcopenic patients, while the sarcopenic patients had a median IC score of 3.5, showing significantly reduced IC. After multivariable analysis, sarcopenic patients had significantly higher impairment in locomotion and vitality domains of IC. Conclusion This study showed that lower IC is associated with sarcopenia. Vitality and locomotion domains are strongly associated with sarcopenia. This study is consistent with hypotheses of shared underlying pathophysiology from prior literature, and hence, sarcopenia and IC should be discussed together while diagnosing and managing an older adult in the Integrated Care for Older People (ICOPE) protocol.
