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
A significant factor in relapse and dismal prognosis of glioblastoma is the migrating glioblastoma cells, which diffuse away from the tumor mass into the brain parenchyma. Post-resection application of biomaterials to deliver cytotoxic agents against the invading glioblastoma cells has recently gained attention. The aim of this study was to develop a non-swelling, non-inflammatory biomimetic hydrogel with sustained release of a chemoattractant for glioblastoma cells and perform in vivo proof-of-concept studies to show chemoattraction of invading glioblastoma cells in orthotopic models of human glioblastoma. We used hyaluronic/collagen II-based (HA/Col) hydrogel that incorporates liposomes loaded with CXCL12 to develop GliaTrap. Sustained release of CXCL12 was measured with an ELISA assay. The non-inflammatory properties of GliaTrap were assessed in-vivo after stereotactic implantation in the mouse brain using a cytokine array and immunohistochemistry. The efficacy of GliaTrap on attracting GSCs was determined in-vivo employing 3D light-sheet microscopy on orthotopic human glioblastoma xenografts. We show that GliaTrap is an injectable, non-swelling biomimetic hydrogel that attains sustained release of CXCL12 and does not induce inflammation in the mouse brain. GliaTrap significantly attracts invading glioblastoma cells in orthotopic xenograft models of human glioblastoma as shown with 3D light sheet microscopy. Our findings indicate that GliaTrap can be safely used to attract invading glioblastoma cells by sustained release of a chemoattractant without inducing inflammatory conditions in the brain or local swelling.
