The Intensity and Pattern of Syndecan-1 (CD138) Expression in Normal and Diseased Livers.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction Heparan sulfate proteoglycans (HSPGs) belong to the syndecan family, and syndecan-1 (CD138) is a heparan sulfate proteoglycan. Syndecan-1 has a potential role in cell-matrix and cell-cell communications as they are present in cell epithelium. Its expression is different in an extensive range of benign, inflammatory, and neoplastic diseases. In routine histopathology, it is used as a marker for plasma cells. However, it is expressed in a large variety of normal and neoplastic epithelia including squamous epithelium and gastric glandular epithelium expressed in other tissues, i.e., the liver. In the liver, variable expression is seen in cirrhosis, hepatitis, and carcinoma. The objective of this study was to investigate the expression of this marker in normal, inflammatory, and neoplastic lesions of the liver. This in turn may help clinicians to select patients who may benefit from anti-CD138 therapy. It is currently used in the diagnosis and management of plasma cell proliferations. Material and methods This is a retrospective study in which we retrieved 53 formalin-fixed paraffin-embedded (FFPE) liver specimen blocks and selected one block from each case by reviewing the hematoxylin and eosin (H&E) slides of each case. Syndecan-1 (CD138), pancytokeratin, and CD68 expression were analyzed immunohistochemically (IHC) to evaluate the percentage and intensity of CD138 expression in various hepatic entities and identify those entities where syndecan-1 can be consistently used to make a definitive diagnosis. Results The expression of pancytokeratin and CD68 was analyzed in hepatocytes and Kupffer cells, respectively. For syndecan-1 (CD138), 15.4% of cases showed basolateral membranous positivity, 44.6% of cases showed complete membranous positivity, and 40% of cases showed no positivity in hepatocytes. Cytokeratin (CK) was positive as expected in hepatocytes, and CD68 was expressed in Kupffer cells. Conclusion CD138 does not appear to be a reliable surrogate marker for liver disease. However, it may be included with other ancillary markers as a predictor of the stage of chronic liver disease and metastatic potential. The response to anti-CD138 therapy needs to be further studied.
