Iron-Induced Hypophosphatemia: A Review of Pathophysiology, Drug Safety, and Pharmacogenomic Perspectives.
Review in Journal of hematology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
Intravenous (IV) iron therapy is a cornerstone in the management of iron deficiency anemia, yet its administration is associated with significant side effects, most notably hypophosphatemia. This adverse event is not a class effect but is disproportionately linked to specific formulations, particularly ferric carboxymaltose (FCM). This review synthesizes the current clinical evidence, elucidates the central pathophysiological role of fibroblast growth factor 23 (FGF23), and explores a potential pharmacogenomic basis for individual susceptibility. Clinical data from numerous randomized controlled trials and meta-analyses confirm that FCM induces hypophosphatemia in over 50% of patients, a rate far exceeding that of other IV iron preparations. The proposed underlying mechanism involves a "two-hit" process: pre-existing iron deficiency upregulates
