Association of inflammatory biomarkers with physical and cognitive frailty in a Spanish population of older adults.
Article in GeroScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Frailty is a multifactorial geriatric syndrome characterized by increased vulnerability to stressors and associated with a higher risk of adverse health outcomes. Chronic low-grade inflammation has been proposed as a key pathophysiological mechanism underlying physical frailty, although its role in cognitive frailty remains undefined. In this cross-sectional study, we assessed the relationship between frailty status, both physical and cognitive, and plasma concentrations of six inflammatory biomarkers-C-reactive protein (CRP), interleukin 6 (IL-6), tumour necrosis factor alpha (TNF-α), soluble TNF-α receptor type II (sTNF-RII), high-temperature requirement serine protease A1 (HTRA1), and growth differentiation factor 15 (GDF15)-in a cohort of Spanish older adults (N = 150, ≥ 65 years old), classified according to Fried's frailty phenotype and frailty index. The results showed notable differences between frailty phenotype and frailty index, and highlighted CRP, TNF-α, sTNF-RII, and GDF15 as key biomarkers significantly associated with physical frailty status, with CRP and TNF-α also discriminating pre-frail individuals. sTNF-RII stood out for its high predictive capacity, while GDF15 added value as an indicator of sustained cellular stress. Regarding cognitive frailty, CRP, TNF-α, and GDF15 displayed significant associations with this condition. sTNF-RII and HTRA1, scarcely studied in this context, showed promising and significant associations (specific for cognitive frailty in the case of HTRA1) that justify their inclusion in future research aimed at better understanding the inflammatory mechanisms involved in cognitive frailty.
