Effect of Amaranth-Containing Dietary Intervention in Improving Hemoglobin Concentration: A Systematic Review and Meta-Analysis.
Synthesis in Public health reviews, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Objective: Amaranth, a nutritious iron source, is known for treating anemia in young children and lactating mothers, but its effectiveness in reducing hemoglobin concentration needs further investigation. Therefore, this study aimed to summarize the effectiveness of amaranth-based food interventions in improving hemoglobin concentration. Method: A randomized controlled trial and quasi-experimental study conducted since 2000 were searched in databases like PubMed, Scopus, Embase, Cochrane, AJOL, and Web of Science using prespecified keywords. Excel and Stata 17 were used for data extraction and analysis. Methodological quality was assessed using the JBI systematic review critical appraisal tool. Meta-analysis was done to estimate the overall intervention effect. Result: Ten studies were included from 1,032 articles (n = 1,225). The standardized mean hemoglobin concentration difference between groups was positive, with an overall effect of 0.08 (95%CI: -0.11, 0.26; p = 0.433), where I Conclusion: The studies' interventions showed positive effects on hemoglobin concentration, but their effectiveness was not statistically significant. This suggests the need for research on the impact of different cooking methods on iron bioavailability, phytic iron ratio, and intervention effects across different populations.
