Transient elastography measurements of the liver and transplanted kidney in patients with AA amyloidosis: a cross-sectional comparative study.

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
To evaluate the utility of elasticity imaging techniques, such as transient elastography (FibroScan), in assessing the liver and transplanted kidney in patients with AA amyloidosis (AA-A). This study was conducted in patients with AA-A, while patients with immunoglobulin light chain amyloidosis (AL-A), Familial Mediterranean Fever (FMF) without amyloidosis, and healthy controls (HC) were included as comparison groups for liver stiffness (LS) measurements. Additionally, kidney stiffness (KS) was measured in renal transplant recipients (RTRs) with transplants due to AA-A or other causes of chronic renal failure. LS evaluations were performed in 65 patients with AA-A, 14 with AL-A, 20 with FMF, and 27 with HC. LS (kPa) was significantly higher [median (IQR)] in patients with AA-A [6.4 (5.4)] and AL-A [9.8 (11)] compared to HC [4.7 (1.7)] (p < 0.001). However, the difference between AL-A and AA-A was not statistically significant. LS values were comparable in FMF-AA patients with [6.8 (6.6)] and without [5.7 (3.6)] liver involvement, and FMF patients without amyloidosis [7.15 (4.6)]. The median KS values were comparable in 19 AA-A and 16 disease controls. However, KS values were significantly higher in patients with recurrent amyloidosis in the transplanted kidney [29.3 (18.9)] compared to those without recurrence [10.9 (7.7)] (p = 0.003). In our study, increased liver stiffness measurements were observed in patients with AA-A, AL-A, and FMF compared to HC. Transient elastography using FibroScan appears to be a promising non-invasive tool for assessing liver involvement in AA-A and may aid in detecting recurrence of amyloidosis in transplanted kidneys. Further studies are needed to validate the utility of FibroScan in evaluating the involvement of the liver and kidneys in patients with AA-A.
