Influence of genetics on the nephritogenic potential of proteoglycans.

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
Nephritogenic potential of antibodies directed against one of the glomerular basement membrane (GBM) components, i.e., heparan sulfate-proteoglycan (HS-PG), was investigated in different strain of rats, i.e., Brown Norway, Lewis, Long Evans, and Sprague-Dawley. The rats were given two intravenous injections of anti-HS-PG antibody on days 1 and 3, and killed 2 to 8 weeks later. Before killing, blood and urine were collected for determination of anti-rabbit IgG levels and excretion of proteins, respectively. In addition, the right kidney was perfused with 125I-anti-rat IgG to quantitate the amount of immune-complexes present within the GBM. The tissues were processed for morphologic, autoradiographic, and immunofluorescent studies. The anti-HS-PG antibody was seen uniformly bound to GBM equally in all strains of rats. However, the protein-uric response was as follows: Brown Norway much much greater than Lewis much greater than Long Evans greater than Sprague Dawley. Also, the glomerular cells, monocytes in the glomerular capillaries, immunoreactivity of rat IgG and C3 frequency of subepithelial immune deposits, serum levels of anti-rabbit IgG, and the amount of 125I-anti-rat IgG bound to the GBM were proportionately increased among different strains of rats. The data suggest that the sustained presence of anti-HS-PG antibodies in the subepithelial aspect of the GBM with differential humoral response in the production of the antibody by the host most likely attributed to the variable glomerular damage in different strains of rats. Thus, it seems that the genetic makeup of a given strain of rat heavily influences the nephritogenic potential of an antibody and consequentially the outcome of the immune complex-mediated glomerular injury.
