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
Human cytomegalovirus (HCMV) is a prevalent viral pathogen, which can cause severe clinical consequences in neonates, immunocompromised individuals, patients with AIDS, and organ and stem cell transplant recipients. HCMV inhibits the host cell cycle progress while the immediate‑early protein 1 (IE1) tethers to condensed chromatin in mitotic cells. The present study investigated the effect of HCMV on the cell cycle in human glioblastoma cells, as well as the role of RhoA GTPase during mitosis in the same context. Live cell microscopy showed that despite the apparent cell cycle arrest at late stages of mitosis in normal fibroblasts, HCMV‑infected U373MG cells successfully went through all stages of cell division. HCMV IE1 protein exhibited a remarkably tight association with mitotic chromosomes from early mitosis to late cytokinesis. Depletion of RhoA significantly impaired the proliferation rate of HCMV‑infected U373MG cells; consistent with this observation, the number of cells entering mitosis was also decreased. These results demonstrated the differential behavior of HCMV during mitosis in a normal and a cancer background. Furthermore, RhoA may be a critical component for the efficient cell division of HCMV‑infected glioblastoma cells, which subsequently ensures the maintenance of viral genomes.
