1 · What the graph read from it

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.

2 · The registry

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

purposeShear wave elastography (SWE) using transabdominal ultrasonography (US) is widely used for diagnosis of tissue stiffness. Ultrasound shear wave dispersion (SWD) enables evaluation of tissue viscosity using SWE. The objective of this study was to investigate the reliability and clinical significance of SWD in pancreatic screening.

methodsSWE and SWD were measured in 76 patients examined by US in pancreatic screenings performed between November 2017 and November 2018. The median pancreatic elastic modulus (PEM) and dispersion slope were obtained from at least five measurements. The reproducibility of these values and their correlations with patient characteristics, pancreatic echogenicity, and the pancreas-to-spleen attenuation ratio (P/S) on plain CT, which is associated with fatty change in pancreatic parenchyma, were investigated retrospectively.

resultsThe median PEM and dispersion slope were 7.4 kPa and 15.7 (m/sec)/kHz, respectively, and both values had high intraclass correlation coefficients, showing high reproducibility (ρ = 0.869 and ρ = 0.867, respectively). The interquartile range/median value of PEM and dispersion slope were 0.36 and 0.28, respectively. PEM had a positive correlation with age (r

conclusionMeasurement of SWD in pancreatic screening was highly reproducible and may permit objective evaluation of fatty change of the pancreas.
