Prosaposin is a novel coenzyme Q10-binding protein.

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
Coenzyme Q10 (CoQ10) is essential for mitochondrial ATP production and functions as an important antioxidant in every biomembrane and lipoprotein. Due to its hydrophobicity, a binding and transfer protein for CoQ10 is plausible, and we previously described saposin B as a CoQ10-binding and transfer protein. Here, we report that prosaposin, the precursor of saposin B, also binds CoQ10. As prosaposin is both a secretory protein and integral membrane protein, it is ubiquitous in the body. Prosaposin was isolated from human seminal plasma, and CoQ10 was extracted from hexane solution into the water phase. It was additionally found that immunoprecipitates of mouse brain cytosol generated using two different anti-prosaposin antibodies contained coenzyme Q9. Furthermore, mouse liver cytosol and mouse kidney cytosol also contained prosaposin-coenzyme Q9 complex. These results suggest that prosaposin binds CoQ10 in human cells and body fluids.
