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

To better understand the tissue iron overload and anemia previously reported in a human patient and mice that lack heme oxygenase-1 (HO-1), we studied iron distribution and pathology in HO-1(Hmox1)(-/-) mice. We found that resident splenic and liver macrophages were mostly absent in HO-1(-/-) mice. Erythrophagocytosis caused the death of HO-1(-/-) macrophages in in vitro experiments, supporting the hypothesis that HO-1(-/-) macrophages died of exposure to heme released on erythrophagocytosis. Rupture of HO-1(-/-) macrophages in vivo and release of nonmetabolized heme probably caused tissue inflammation. In the spleen, initial splenic enlargement progressed to red pulp fibrosis, atrophy, and functional hyposplenism in older mice, recapitulating the asplenia of an HO-1-deficient patient. We postulate that the failure of tissue macrophages to remove senescent erythrocytes led to intravascular hemolysis and increased expression of the heme and hemoglobin scavenger proteins, hemopexin and haptoglobin. Lack of macrophages expressing the haptoglobin receptor, CD163, diminished the ability of haptoglobin to neutralize circulating hemoglobin, and iron overload occurred in kidney proximal tubules, which were able to catabolize heme with HO-2. Thus, in HO-1(-/-) mammals, the reduced function and viability of erythrophagocytosing macrophages are the main causes of tissue damage and iron redistribution.
