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

Anterior-posterior polarity of the mouse embryo has been thought to be established when distal visceral endoderm (DVE) at embryonic day (E) 5.5 migrates toward the future anterior side to form anterior visceral endoderm (AVE). Lefty1, a marker of DVE and AVE, is asymmetrically expressed in implanting mouse embryos. We now show that Lefty1 is expressed first in a subset of epiblast progenitor cells and then in a subset of primitive endoderm progenitors. Genetic fate mapping indicated that the latter cells are destined to become DVE. In contrast to the accepted notion, however, AVE is not derived from DVE but is newly formed after E5.5 from Lefty1(-) visceral endoderm cells that move to the distal tip. Concomitant with DVE migration, all visceral endoderm cells in the embryonic region undergo global movement. In embryos subjected to genetic ablation of Lefty1-expressing DVE cells, AVE was formed de novo but the visceral endoderm including the newly formed AVE failed to migrate, indicating that DVE guides the migration of AVE by initiating the global movement of visceral endoderm cells. Future anterior-posterior polarity is thus already determined by Lefty1(+) blastomeres in the implanting blastocyst.
