Investigation of the mechanical frequency response of ovine renal tissue at low frequencies.
Article in Scientific reports, 2025. 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
This study explores the mechanical properties of ovine renal tissue, focusing on resonance patterns at low frequencies. Using a universal tensile/compression testing machine, we examined the stress-strain behavior of the tissue under compression, revealing its non-linear viscoelastic characteristics. Dynamic Mechanical Analysis (DMA) and a dynamic shear rheometer were employed to measure the storage and loss moduli across various frequencies (0.01-10 Hz). The shear storage modulus ranged from 1 kPa to 48 kPa in the strain level of 0.5%, while the shear loss modulus varied between 2 kPa and 4 kPa. Experimental results showed no resonant behavior in the mechanical properties, including storage modulus, loss modulus, and tan delta, in both tensile and shear modes at frequencies below 10 Hz. A vibration test was conducted using a shaker to investigate the Frequency Response Function (FRF) of the kidney over the studied frequency range. The vibration tests revealed mechanical resonance in the kidney at approximately 3 Hz. A numerical modal analysis, conducted using COMSOL software, identified a natural frequency around 3 Hz, closely aligning with experimental observations. These findings suggest significant implications for understanding renal mechanics and developing medical applications.
