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
purposeTo evaluate the rate of hyperechoic liver lesions that are clinically actionable and evaluate imaging and clinical factors associated with these to determine the need for follow-up. MATERIALS AND
methodsThis retrospective study included 228 hyperechoic hepatic lesions on ultrasound in 228 patients. Reference standards included either dynamic contrast enhanced MRI (n = 130) or CT (n = 46), follow-up ultrasound performed at least 2 years from baseline (n = 50), or histopathology (n = 2). Three radiologists independently assessed imaging features including lesion orientation, degree of hyper-echogenicity, lesion heterogeneity, and background liver echotexture. Univariable and multivariable logistic regression was used to determine features associated with an actionable hyperechoic lesion.
resultsOf the 228 hyperechoic lesions, 14 (6.1%) lesions were clinically actionable (or requiring follow-up), and 214 (93.9%) were clinically insignificant. Features that differed between patients with clinically insignificant vs. actionable lesions included: age (52.9 ± 15.1 vs. 63.9 ± 15.8 years, p = 0.004), male sex (43.9% vs 71.4%, p = 0.045), history of cirrhosis (6.5% vs 50%, p < 0.001), lesion size (1.9 ± 1.4 cm vs. 3.5 ± 2.8 cm, p = 0.003), heterogeneous lesion echogenicity (16.4% vs. 50%, p = 0.006), and cirrhotic/coarsened background liver (7.5% vs. 35.7%, p = 0.005). Stepwise logistic regression and multivariable analysis identified age, presence of cirrhosis, and lesion size as features most predictive of an actionable lesion (OR 1.04, 24.3, 1.77 respectively). Reader agreement for imaging features was fair to moderate (k = 0.29-0.53). 100%(168/168) of hyperechoic liver lesions measuring ≤ 3 cm in patients without a history of malignancy or underlying liver disease were clinically insignificant.
conclusionOur study findings support the overall favorable diagnoses of hyperechoic liver lesions ≤ 3 cm in patients without underlying risk factors.
