Improved recovery from spinal cord injury in rats with chronic parvovirus serotype-1a infection.
Article in Spinal cord, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesA vendor informed us that rats shipped to us and used by us in a spinal cord contusion injury experiment were infected by rat parvovirus type 1a (RPV-1a). Our aim was therefore to determine whether this infection may have altered locomotor recovery or tissue pathology.
settingStockholm, Sweden.
methodsWe induced a moderate contusion injury of the spinal cord in rats received from an (unknown to us) RPV-1a-contaminated facility. We compared the hind limb locomotor function between RPV-1a-infected rats and non-infected controls with the same spinal cord lesions, obtained before (historical control), as well as after infection (future controls). Histologically, we assessed spinal tissue sparing, astrocyte reactivity and the amount of macrophages/activated microglia.
resultsRPV-1a-infected rats had significantly better hind limb locomotor recovery compared with both 'historical' and 'future' controls. We also observed significantly better tissue sparing and axonal sparing around the injury site, as well as significant reductions in macrophages/activated microglia and astrocyte reactivity in the spinal cords of RPV-1a-infected rats.
conclusionThe results stress the importance of knowing the health status of animals used to study central nervous system trauma and support the notion that acquired infections, even if asymptomatic, may alter response to injury in mammals. Furthermore, the results demonstrate that virus infections may have positive effects on functional recovery after spinal cord injury and indicate that RPV-1a infection may be neuroprotective by dampening secondary damage.
