Seismocardiography for nonexercise estimation of cardiorespiratory fitness in older adults.
Article in BMC geriatrics, 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
introductionCardiorespiratory fitness predicts health and longevity. The gold-standard test for V̇O₂-peak, the cardiopulmonary exercise test (CPET), is difficult to conduct in older adults, and alternative methods offer low to moderate accuracy. This project compared a new method, seismocardiography, to CPET in older adults. It was hypothesized that seismographic V̇O₂-peak estimates would strongly correlate with CPET-derived V̇O₂-peak.
methodThirty-six healthy older adults (aged 65-75 years; 19 female) completed the seismocardiography assessment (Seismofit
resultsThe sample had a mean age of 70 ± 3.0 years and BMI of 25.7 ± 2.8 kg/m². For all participants, a significant positive correlation was observed between Seismofit
conclusionThis study demonstrated that Seismofit show a moderate-to-strong association with CPET measurements in older adults. Seismofit, however, systematically overestimated V̇O₂-peak. For Seismofit to be integrated into large-scale cohort studies and experimental research, the methodology used for older adults needs further development.
