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

Background Hereditary hemorrhagic telangiectasia ( HHT ) is a rare genetic vascular disorder caused by mutations in endoglin ( ENG ), activin receptor-like kinase 1 ( ACVRL 1; ALK 1), or SMAD 4. Major clinical symptoms of HHT are arteriovenous malformations ( AVM s) found in the brain, lungs, visceral organs, and mucosal surface. Animal models harboring mutations in Eng or Alk1 recapitulate all of these HHT clinical symptoms and have been useful resources for studying mechanisms and testing potential drugs. However, animal models representing SMAD 4 mutations have been lacking. The goal of this study is to evaluate Smad4-inducible knockout ( iKO ) mice as an animal model of HHT and compare the phenotypes with other established HHT animal models. Methods and Results Global Smad4 deletion was induced at neonatal and adult stages, and hemoglobin levels, gastrointestinal hemorrhage, and presence of aberrant arteriovenous connections were examined. Neonatal Smad4- iKO mice exhibited signs of gastrointestinal bleeding and AVM s in the brain, intestine, nose, and retina. The radial expansion was decreased, and AVM s were detected on both distal and proximal retinal vasculature of Smad4- iKO s. Aberrant smooth muscle actin staining was observed in the initial stage AVM s and their connecting veins, indicating abnormal arterial flow to veins. In adult mice, Smad4 deficiency caused gastrointestinal bleeding and AVM s along the gastrointestinal tract and wounded skin. HHT -related phenotypes of Smad4- iKO s appeared to be comparable with those found in Alk1- iKO and Eng- iKO mice. Conclusions These data further confirm that SMAD signaling is crucial for normal arteriovenous network formation, and Smad4- iKO will be an alternative animal model of AVM research associated with HHT .
