1 · What the graph read from it

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.

2 · The registry

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 male genital tract is diverse among vertebrates, but its development remains unclear, especially in the rete region. In this study, we investigated the testis-mesonephros complex of rabbit, chicken, and frog (Xenopus tropicalis) by immunohistochemistry for markers such as Ad4BP/Sf-1 (gonadal somatic and rete cells in mammals) and Pax2 (mesonephric tubules), and performed a three-dimensional reconstruction. In all investigated animals, testis cords were bundled at the mesonephros side. Rete cells positive for Ad4BP/Sf-1 (rabbit) or Pax2 (chicken and frog) were clustered at the border region between the testis and mesonephros. The cluster possessed two types of cords; one connected to the testis cords and the other to the mesonephric tubules. The latter rete cords were contiguous to Bowman's capsules in rabbit and chicken but to nephrostomes in frog. In conclusion, this study showed that mammals, avian species, and frogs commonly develop the bundle between the testis cords (testis canal) and the cluster of rete cells (lateral kidney canal), indicating that these animals share basic morphogenesis in the male genital tract. The connection site between the rete cells and mesonephric tubules is suggested to have changed from the nephrostome to the Bowman's capsule during vertebrate evolution from anamniote to amniote.
