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

In clinical practice, intravenous (IV) iron therapy is used for the correction of iron deficiency. Patients with chronic causes of iron deficiency, for example, women with abnormal uterine bleeding, patients with inflammatory bowel disease often require repeated dosing with IV iron therapy. After a single standard dose of IV iron therapy (1000 mg) with ferric carboxymaltose, there is a rapid intake of iron into the myocardium, resulting in a sustained increase in myocardial iron content. The increase in myocardial iron content is independent of changes in plasma ferritin levels, and the recurrence of iron deficiency is not accompanied by a normalisation of myocardial iron. The most important implication is that repeated dosing with IV iron (ferric carboxymaltose) can result in cumulative build-up of iron in the myocardium.
