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
objectiveAnnexin A1 (ANXA1) is a calcium-dependent phospholipid-binding protein which contributes to proliferation, cancer progression and metastasis. Overexpression of ANXA1 is closely associated with metastasis in numerous types of cancer. Cholangiocarcinoma (CCA) is a bile-duct cancer which has high rates of metastasis. Previously, we demonstrated up-regulation of ANXA1 in a highly metastatic CCA cell line (KKU-213AL5). Here, we investigated the functions of ANXA1 in the progression of CCA cell lines and evaluated its clinical impacts in human CCA tissues. Methods: Effects of ANXA1 on metastatic potential of CCA cell lines were evaluated using cell-proliferation, clonogenic, migration and invasion assays. The expression of ANXA1 in 44 intrahepatic human CCA tissues was investigated using immunohistochemistry (IHC). The association of ANXA1 with clinicopathological features of CCA patients was analyzed.
resultsSilencing of ANXA1 expression using siRNA significantly decreased cell proliferation, colony formation, cell migration and invasion in the KKU-213AL5 cell line. IHC results showed low expression of ANXA1 in normal bile ducts in the non-tumor area. In contrast, high expression of ANXA1 in human CCA tissues was associated with advanced tumor stage, tumor size and presence of lymph-node metastasis.
conclusionThese findings strongly imply that ANXA1 contributes to the progression of CCA. ANXA1 can serve as a potential prognostic marker for CCA. Ablation of ANXA1 action may be an alternative strategy to prevent metastasis of CCA.
