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
backgroundIn light of increasing therapeutic options, risk stratification of advanced cardiac transthyretin amyloidosis (ATTR-CA) is gaining clinical importance to avoid ineffective treatments. Liver stiffness as a marker of hypervolemia and hepatic congestion might predict mortality in advanced ATTR-CA and allow to identify patients at highest risk.
methodsProven ATTR-CA patients underwent repeated vibration-controlled transient elastography (VTCE) and standardized serial workup within the local amyloidosis cohort study AmyKoS. Spearman correlation analyses and Cox regressions were performed to evaluate the prognostic value.
results41 patients with ATTR-CA were included with median age of 76.6 (55.1-89.1) years, of which 90.2% were male and > 92% wild-type ATTR-CA. In total, 85 VCTE examinations were performed. Median follow-up was 43.7 (2.4-75.6) months; 26.8% of the patients died. At the first clinical evaluation, median left ventricular (LV) absolute global longitudinal strain (GLS) was 11.4 (5.2-19.0) % and median liver stiffness was 6.3 (2.4-22.9) kPa, both significantly correlated with mortality. NT-proBNP possessed statistically significant predictive power in ATTR-CA with more preserved LV function (absolute GLS ≥ 10), whereas stiffness seemed to be more discriminative for ATTR-CA with absolute GLS < 10. The use of alternative congestion surrogates such as liver vein dilation and tricuspid regurgitation peak velocity (tr-v
conclusionLiver stiffness shows prognostic value regarding all-cause mortality and allows risk stratification in advanced ATTR-CA, particularly in those with markedly impaired longitudinal LV function. These results are transferable to other congestion surrogates.
