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

Background: There is frequently ambiguity regarding the optimal utilization of the liver protocol or the pancreas protocol, and the selection between HAP and PPP is often the subject of controversy. The purpose of this study is to evaluate the validity and efficacy of newly developed hepatopancreatic arterial-dominant phase (HPAP) imaging, which synchronizes HAP and PPP using the partial downslope injection technique (pDiT), compared with conventional HAP and PPP in detecting pancreatic ductal adenocarcinoma. Materials and methods: This retrospective study included 130 examinations with pancreatic ductal adenocarcinoma who underwent pancreatic CT using either pDiT or a standard injection technique between November 2023 and June 2025. The injection duration was 30-second. The pDiT used 360 mgI/kg at 80 kVp, consisting of a 10-second constant injection followed by a 20-second downslope injection with a slope index (end injection rate / initial injection rate) of 0.3. The standard injection technique used 600 mgI/kg at 120 kVp with a constant rate. Pancreas-to-lesion contrast (PLC), contrast-to-noise ratio (CNR), lesion conspicuity, and sensitivity were compared among HAP, PPP, and HPAP. Results: Mean PLC and CNR were significantly higher with HPAP than with HAP ( Conclusion: HPAP generated using the pDiT provides optimal arterial-phase imaging for pancreatic CT.
