Undegraded chromogranin A is present in serum and enters the endocytotic lysosomal pathway in kidney.
Article in Histochemistry, 1991. 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
Analysis of human and bovine serum by immunoblotting revealed the presence of the proprotein chromogranin A. By the same method chromogranin A was also found in rat, bovine and human kidney. However this organ did not contain any chromogranin A mRNA arguing against a synthesis within this organ. By immune-electron microscopy chromogranin A immunoreactivity was found in proximal tubule cells of rat kidney. Positive immunostaining was present in small vesicles within and in close proximity to the brush border and closer to the nucleus in typical lysosomal structures. These results make it likely that chromogranin A from serum reaches kidney tubule cells by glomerular filtration and is taken up into the endocytotic lysosomal pathway.
