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
backgroundMalignant tumors release growth factors, promoting lymphangiogenesis in primary tumors and draining sentinel lymph nodes, ultimately facilitating lymph node metastasis. As a malignant lymphatic tumor entity, lymphangiosarcomas are characterized by low survival rates and limited treatment options. The transcription factor SOX18 plays a crucial role in both lymphatic endothelial cell differentiation and cancer-induced lymphangiogenesis.
aimsIn this in vitro study, we investigated the potential therapeutic effect of a small molecule called Sm4, which inhibits SOX18, on lymphatic endothelial and lymphangiosarcoma cells in vitro. METHODS AND
resultsHuman dermal lymphatic endothelial cells (HDLECs), lymphangiosarcoma cells (MO-LAS), and other endothelial cell lines were cultured. We found that Sox18 exhibited high mRNA expression levels in both HDLEC and MO-LAS. Sm4 treatment decreased the Sox18 expression level at the mRNA and protein levels in both HDLEC and MO-LAS significantly, a phenomenon confirmed through immunofluorescence images. Additionally, Sm4 treatment suppressed the expression of key lymphatic phenotype markers (Prox1, Flt4, and Lyve1) and hindered migration in both HDLEC and MO-LAS, all while maintaining cell viability.
conclusionThese findings suggest that targeting SOX18 with Sm4 may hold potential as a therapeutic strategy for lymphangiosarcoma and cancer-induced lymphatic metastasis. Further in vitro studies are warranted to investigate the mechanisms and conduct dose-response analyses to evaluate Sm4's potential as a targeted therapy for lymphangiosarcoma and cancer-induced lymphangiogenesis in the future.
