Clinical application of subharmonic aided pressure estimation (SHAPE) in the assessment of portal hypertension in patients with decompensated cirrhosis: A pilot study.
Article in Clinical hemorheology and microcirculation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 1 paper.
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
PurposeThe aim of the study was to explore the possibility of subharmonic aided pressure estimation (SHAPE) measurement for noninvasive evaluation of portal hypertension in patients with decompensated liver cirrhosis.Materials and MethodsPatients diagnosed with decompensated liver cirrhosis were prospectively enrolled. SHAPE measurement was performed by using an ultrasound system. A continuous infusion of sonazoid at a rate of 0.18 ml/kg/h and saline at 120 ml/h was performed. The hepatic venous pressure gradient (HVPG) value are the gold standard for evaluating portal hypertension. The Pearson coefficient and areas under the receiver operating characteristic curves (AUCs) were analyzed.ResultsFrom February 2023 to August 2023, 15 patients (mean age, 61.1 ± 8.3 years; eight men and seven women) were included. The correlation coefficient of the SHAPE gradient and HVPG was 0.33. The mean SHAPE gradient of patients with clinically significant portal hypertension (CSPH) (HVPG ≥ 10 mmHg) was significantly higher than that of patients with lower risk (0.5 ± 4.4 dB vs. -7.4 ± 5.1 dB,
