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

Hepcidin is the key regulator of iron absorption and recycling, and its expression is suppressed by red blood cell production. When erythropoiesis is expanded, hepcidin expression decreases. To gain insight into the stage of erythroid differentiation at which the regulation might originate, we measured serum hepcidin levels in archived pure red cell aplasia samples from patients whose block in erythroid differentiation was well defined by hematopoietic colony assays and marrow morphologic review. Hepcidin values are high or high normal in pure red cell aplasia patients in whom erythropoiesis is inhibited prior to the proerythroblast stage, but are suppressed in patients with excess proerythroblasts and few later erythroid cells. These data suggest that the suppressive effect of erythropoietic activity on hepcidin expression can arise from proerythroblasts, the stage at which transferrin receptor 1 expression peaks, prompting the hypothesis that transferrin receptor 1 expression on erythroid precursors is a proximal mediator of the erythroid regulator of hepcidin expression. Our characterization of erythropoiesis, iron status, and hepcidin expression in mice with global or hematopoietic cell-specific haploinsufficiency of transferrin receptor 1 provides initial supporting data for this model. The regulation appears independent of erythroferrone and growth differentiation factor 15, supporting the concept that several mechanisms signal iron need in response to an expanded erythron.
