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
backgroundCholangiocarcinoma (CCA) is an aggressive malignancy with limited treatment options and poor prognosis. Platelet-Derived Growth Factor CC (PDGF-CC) has been implicated in the progression of various tumors, but its specific role in CCA is not well understood. This study aims to investigate the expression and function of PDGF-CC in CCA and evaluate its potential as a therapeutic target.
methodsWe conducted gene expression analysis using the GEPIA database to compare PDGF-CC mRNA levels in CCA tissues and normal tissues. Serum samples from CCA patients were analyzed for PDGF-CC protein levels, and immunohistochemistry was used to assess PDGF-CC expression in tissue samples. The impact of PDGF-CC on CCA cell behavior was examined by knocking out PDGF-CC in HuCCT1 and QBC939 cell lines, followed by assessments of cell proliferation, migration, invasion, and colony formation in vitro. Additionally, the effects of PDGF-CC knockout were evaluated in xenograft models. The therapeutic potential of PDGF-CC inhibition was further explored using pharmacological inhibitors and antibodies.
resultsPDGF-CC mRNA and protein levels were significantly elevated in CCA tissues and patient sera compared to normal controls. Immunohistochemical analysis confirmed increased PDGF-CC expression in CCA tissues. High PDGF-CC expression correlated with poor overall survival in CCA patients, as shown by Kaplan-Meier analysis. Functional assays revealed that PDGF-CC knockout significantly reduced proliferation, migration, invasion, and colony formation in HuCCT1 and QBC939 cells, the lines with the highest PDGF-CC levels. In vivo, PDGF-CC knockout markedly decreased tumor growth in xenograft models. Pharmacological inhibition of PDGF-CC mirrored the effects of genetic knockout, suggesting it as a viable therapeutic strategy.
conclusionsThis study underscores the critical role of PDGF-CC in CCA progression and supports the potential of PDGF-CC inhibitors as a therapeutic approach. Given the association between high PDGF-CC expression and poor prognosis, targeting PDGF-CC may improve outcomes for CCA patients. Further clinical investigations are warranted to develop PDGF-CC-targeted therapies for CCA.
