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
Oxidative stress hurts the survival of transplanted mesenchymal stem cells (MSCs). Lipopolysaccharide (LPS) preconditioning inhibits apoptotic death in MSCs. Also, Lovastatin's protective effect was reported on MSCs. Here, we investigated the potential of LPS and Lovastatin combination therapy on the survival and proliferation of MSCs. MSCs harvested from adult rats (240-260 g) femur and tibia bone marrow. Third passage MSCs were divided into 6 groups control group, LPS, LPS + Lovastatin (10 and 15 µM), and Lovastatin (10 and 15 µM). Cell survival and proliferation were assessed using an MTT assay 24 h after LPS, Lovastatin, or LPS + Lovastatin treatment. Also, Malondialdehyde (MDA) as a lipid peroxidation marker and antioxidant enzymes such as Glutathione peroxidase (GPX) and Superoxide dismutase (SOD) activity levels evaluated. Finally, the expression level of tumor protein P53 (P53) and octamer-binding transcription factor 4 (OCT4) genes were measured by qRT-PCR test. Lovastatin 10 μM potentiated proliferation and survival of MSCs. It can increase the activity of GPX and SOD. 10 µM Lovastatin could not affect MDA amounts but decreased the expression levels of P53 and Oct4 significantly. Nevertheless, treatment with LPS reduced the survival and proliferation of MSCs, along with a significant reduction in GPX activity. LPS + Lovastatin could increase SOD activity, however, GPX enzyme activity and MSCs proliferation did not change so, and it was not effective. We propose Lovastatin at the dose of 10 µM as a suitable combination agent to increase the survival and proliferation of MSCs in oxidative stress conditions.
