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

backgroundUrethral groove (UG) formation is an important step in penile formation. Because commonly used animal models do not have UG, the mechanisms of UG formation have never been discovered. We aim to discover the cellular mechanism of the UG formation using guinea pig model.

methodsHistology was used to study the ontogeny of UG. BrdU immunofluorescence was used to label proliferating cells, cell death was determined using LysoTracker Red and TUNEL staining, and stereology was used for quantification. To reveal Shh mRNA expression patterns, in situ hybridization was performed in guinea pig genital tubercles (GTs) and Shh

resultsCell proliferation in the outer layers and programmed cell death in the inner layers of urethral epithelium played key roles during urethral canal movement from dorsal to ventral aspect and final opening to form UG. Shh mRNA expression domain shifted out to the ventral surface of GT from proximal throughout to distal in guinea pigs, but was excluded from the ventral surface epithelium in midshaft and distal of mouse GT.

conclusionDifferential cell proliferation and cell death in developing urethral epithelium lead to UG formation and Shh expression in ventral surface epithelium of GT may play an important role.
