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
backgroundPancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies. Regardless of surgical resection, chemotherapy acts as the first-line treatment for PDAC. However, the clinical outcomes are severely compromised by insufficient tumour-specific targeting, chemoresistance, and systemic toxicity. Thus, new synergistic therapeutic strategies are urgently needed to improve therapeutic efficacy of PDAC. PURPOSE: This study developed a glypican-1 (GPC1)-targeted and low-intensity focused ultrasound (LIFU)-responsive nanoplatform for visualized treatment against PDAC.
methodsThis nanoplatform, termed GCPIP, integrated glypican-1-antibody (GPC1-Ab)-guided tumour-specific targeting, perfluoropentane (PFP)-driven acoustic imaging, ultrasound targeted nanobubble destruction (UTND)-triggered drug release, paclitaxel (PTX)-mediated chemotherapy and sonosensitizer-assisted sonodynamic therapy (SDT).
resultsGCPIP exhibited favourable physicochemical properties as a delivery system, showing excellent stability, responsive drug release behaviour, and robust ROS-generating capacity. In vitro studies revealed that GCPIP exhibited outstading tumour-targeting capability and potent inhibitory activity against PDAC tumour cells. Near-infrared fluorescence (NIRF) imaging in vivo demonstrated that GCPIP displayed a biodistribution profile broadly consistent with typical metabolic fate of nanoparticles, enabling preferential intratumoural accumulation. Leveraging acoustic droplet vaporization (ADV) effect of PFP, ultrasound (US) imaging further allowed real-time visualization of the uptake and spatial distribution of GCPIP within the tumour. Importantly, GCPIP elicited a pronounced synergistic antitumour effect upon LIFU, as evidenced by substantial inhibition in both tumour volume and tumour weight. Additionally, GCPIP exhibited favourable biosafety in vivo.
conclusionGCPIP successfully achieved US imaging, tumour-specific drug delivery, spatiotemporally controlled drug release, and amplified chemo-sonodynamic therapy, providing a promising strategy to overcome chemoresistance of PDAC and reduce systemic toxicity.
