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 process of iron transport across the blood-brain barrier (BBB) includes two transmembrane steps: step 1, iron in circulating blood first passes through the luminal membrane (blood side) of BBB cells; step 2, it then passes through the abluminal membrane of the cell (cerebroside) and eventually enters the brain. Compared with step 1, we know relatively little about the mechanism of step 2. However, a large number of studies conducted in the past two decades since the discovery of ferroportin 1 (Fpn1) in 2000 has greatly enhanced our understanding of this issue. Accumulating evidence suggests that Fpn1 is a key player in step 2 and that Fpn1/hephaestin and/or Fpn1/ceruloplasmin iron export pathways found in the basement membrane of intestinal enterocytes have the same role in step 2. In this Review, we focus on the current understanding of the role of Fpn1 in iron transport across the abluminal membrane of the BBB.
