Article in Neurochemical research, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03979742 (A Randomized Controlled Phase II, Two-Arm Study of Umbilical Cord Blood Cell Transplant), which is not on this map. Cited by 8 papers.

1 · What the graph read from it

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.

Abstract

We investigated the involvement of tPA after SCI in rats and effect of treatment with human umbilical cord blood derived stem cells. tPA expression and activity were determined in vivo after SCI in rats and in vitro in rat embryonic spinal neurons in response to injury with staurosporine, hydrogen peroxide and glutamate. The activity and/or expression of tPA increased after SCI and reached peak levels on day 21 post-SCI. Notably, the tPA mRNA activity was upregulated by 310-fold compared to controls on day 21 post-SCI. As expected, MBP expression is minimal at the time of peak tPA activity and vice versa. Implantation of hUCB after SCI resulted in the downregulation of elevated tPA activity/expression in vivo in rats as well as in vitro in spinal neurons. Our results demonstrated the involvement of tPA in the secondary pathogenesis after SCI as well as the therapeutic potential of hUCB.
