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

Background and objectives: Exclusively breastfed infants are at risk of iron deficiency due to the low iron content in breast milk. This study aims to evaluate the benefits and risks of daily oral iron supplementation on growth, cognitive outcomes, and hematologic parameters in these infants. Methods: Data sources include Cochrane Central Register of Controlled Trials, PubMed, and Embase from inception to December, 2024. Randomized controlled trials were included. The Cochrane risk of bias tool was used to assess the methodological quality of included trials. The continuous outcomes were analyzed by calculating the mean difference (MD) and the binary categorical variables were analyzed using relative risk (RR) with 95% confidence intervals (CI). Results: This study included 8 trials (685 participants) comparing iron supplementation to no iron. At 6 months of age, compared to infants who were exclusively breastfed without iron supplementation, those who received oral iron supplementation showed an increase in hemoglobin (Hb) levels (MD 0.42, 95% CI 0.19-0.66, Conclusions: Limited available evidence suggests that iron supplementation is beneficial for hematologic parameters and the incidence of IDA in healthy exclusively breastfed infants. However, it may delay weight gain and head circumference growth. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/, PROSPERO [CRD42024610082].
