Expression of VIP and its receptors in the testis of the spotted ray Torpedo marmorata (Risso 1880).

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
The aim of this work was to study, by immunoprecipitation, in situ hybridization and immunohistochemistry, and the expression of the vasoactive intestinal peptide (VIP) and of its receptors (VPAC(1)R and VPAC(2)R) in the testis of a nonmammalian vertebrate, the cartilaginous fish Torpedo marmorata. We demonstrated that, differently from mammals, VIP and VPAC(2)R were widely distributed in the testicular cells while the VPAC(1)R had a limited distribution. In details, we showed that VIP and VPAC(2)R were present in mitotic and differentiating germ cells as well as in the cells involved in the steroidogenesis, i.e., Leydig, Sertoli cells, and prespermatogonia and spermatogonia. The possibility that VIP is involved in the spermatogenesis and particularly in the steroidogenesis of T. marmorata is discussed.
