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
In 3-month bone marrow transplants of CBA mice from bone marrow donors receiving single injections of TLR-4 ligand (LPS) or NOD-2 ligand (muramyl dipeptide, MDP) 24 h before transplantation, an increase in the total number of MSCs (by 2.6 and 1.9 times, respectively), as well as a slight increase in the number of nuclear cells and the mass of bone capsules (by 1.3 and 1.2 times) were observed. After combined administration of MDР and LPS to donors, the total content of MSCs in the grafts was higher by 1.6 times in comparison with the total result of their isolated administration (and by 7.2 times in comparison with the control). At the same time, the concentration of osteogenic MSCs in the grafts of all groups was almost the same and corresponded to the control level. The number of nuclear cells and the mass of bone capsules of the grafts after combined administration of LPS and MDP were close (~80%) to the sum of the results of their isolated administration. These findings suggest that activation of the stromal tissue and the success of bone marrow transplantation depend on the intensity of innate immune responses. These data can be useful for the development of optimal methods of tissue transplantation.
