A method to establish a mouse model of bone marrow microenvironment injury.
Article in Experimental animals, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 normal bone marrow microenvironment plays a very important role in the normal functioning of hematopoietic stem cells. Once disturbed, this microenvironment can become favorable for the occurrence of blood disorders, cancers, and other diseases. Therefore, further studies on the bone marrow microenvironment should be performed to reveal regulatory and stem cell fate determination mechanisms and promote the development of bone marrow transplantation, tissue repair and regenerative medicine, and other fields. A small animal model for further research is also urgently needed. In this study, an electric shock device was designed to elicit a femur bone marrow microenvironment injury in mice. A wire was inserted into the distal femur but not into the proximal femur, and the bone marrow microenvironment was evidently damaged by application of 100 ± 10 V for 1.5 ± 0.5 min ; mortality, however, was low in the mice. Gross observation, hematoxylin and eosin staining, immunohistochemistry, bright-field microscopy, and micro-CT scanning were also conducted. A large number of new blood capillaries and sinusoids appeared in the injured distal femur after 2 weeks. The capillaries in the injured femur disappeared after 4 weeks, and mature blood vessels were scattered throughout the injured area. Red blood cells disappeared, and the cellular structure and trabecular bone were better than those observed 2 weeks previously. Thus, we developed a simply operated, accurate, reliable, and easily controlled small animal model as a good technical platform to examine angiogenesis and segmentation damage in the bone marrow microenvironment.
