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
Multiple myeloma (MM) is a neoplastic condition resulting from the uncontrolled expansion of B-cell-derived plasma cells. The importance of angiogenesis in MM development has also been demonstrated. Extracellular vesicles (EVs) have vital functions in interactions between neighboring cells, such as angiogenesis. The objective of this in vitro study was to examine the transfection and angiogenesis effects of MM-EVs on endothelial cells (ECs) upon treatment with Tetrahydroisoquinoline (THIQ) as a bioactive organic compound derivative from isoquinoline. Following treatment of multiple myeloma cells (U266) with THIQ, MM-EVs were harvested and transmigrated to human umbilical vein endothelial cells (HUVEC) in a co-culture model. EVs transmigration was traced by flow cytometry. Correspondingly, the expression of angiogenic genes and/or proteins in U266 cells and HUVECs was measured by RT-PCR and ELISA methods. Likewise, the proliferation and migration of HUVECs treated with THIQ-treated MM-EVs were visualized and estimated by performing both tube formation and scratch wound healing methods. Surprisingly, the anti-angiogenic effect of THIQ-treated MM-EVs was evident by the decreased expression of CD34, VEGFR2, and IL-6 at the mRNA and/or protein levels after internalization of MM-EVs in HUVEC. Finally, tube formation and scratch wound healing experiments showed inhibition of HUVEC cell proliferation and migration by THIQ-treated MM-EVs compared to control MM-EVs. MM-EVs derived from THIQ-treated myeloma cells (U266) inhibited angiogenesis in HUVECs. This phenomenon is coordinated by the internalized THIQ-treated MM-EVs in HUVECs, and ultimately the reduction of angiogenic factors and inhibition of tube formation and scratch wound healing.
