Preclinical perspectives on common iron fortificants and their bioavailability in rat models: a systematic review and meta-analysis.
Synthesis in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Numerous preclinical studies on improving iron bioavailability to address iron deficiency anemia have been published; however, no preclinical systematic reviews with pairwise meta-analyses have been conducted. Therefore, it is essential to systematically review, summarize, and evaluate the evidence regarding the effects of iron fortificants in animal studies. Methods: The initial articles were identified in four scientific databases (PubMed, Web of Science Core Collection, Scopus, and EBSCO) on 10 January 2026. The final included articles were collected after the initial articles were scanned and sorted. The data were extracted for pairwise meta-analysis. Hemoglobin (Hb) was the primary outcome. Results: A total of 23 studies were included in this systematic review. Data from 13 rat experiments, including 56 comparisons, were analyzed using pairwise meta-analysis. The results of the meta-analysis showed that the overall effects of sodium iron ethylenediaminetetraacetate (NaFeEDTA) and ferrous fumarate on Hb were equivalent to those of ferrous sulfate (FeSO Conclusion: The meta-analysis results suggest that both NaFeEDTA and ferrous fumarate are effective in improving Hb concentration.
