The use of streptolysin o for the treatment of scars, adhesions and fibrosis: initial investigations using murine models of scleroderma.

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
Diseases and conditions involving the deposition of excessive amounts of collagen include scleroderma, fibrosis, and scar and surgical adhesion formation. Diseases such as scleroderma may result from acute and chronic inflammation, disturbances in the normal parenchymal area, and activation of fibroblasts. ML-05, a modified form of the hemolytic and cytotoxic bacterial toxin, streptolysin O, is being developed for the treatment of such collagen-related disorders. At sublytic concentrations in vitro, ML-05 was shown to activate CD44 expression. This may modulate production of collagen, hyaluronate, and their associated enzymes to allow a restoration of normal extracellular matrices within tissues. More importantly, ML-05 appeared to decrease skin collagen levels in two in vivo models of collagen disorders, the tight skin mouse (Tsk) model of scleroderma, and the bleomycin-induced mouse skin fibrosis model. In the Tsk model, levels of hydroxyproline (a measure of total collagen) decreased by 25% in the Tsk+ML-05 treatment group relative to the Tsk+saline control group over a 3-month period. In the bleomycin-induced skin fibrosis study, hydroxyproline levels decreased from 15-22% over a 6-week period in a bleomycin-induced ML-05 treatment group (relative to levels in a bleomycin-induced, untreated control group). Hydroxyproline levels in samples from this treatment group were only slightly greater than levels in an uninduced control group at 8 weeks. Thus, ML-05 treatment appeared to reduce collagen levels in two separate mouse skin fibrosis models, one genetically based and the other chemically induced.
