Evaluating the Mentzer Index for Screening of Iron Deficiency Anemia and Beta Thalassemia Among Infants Visiting Primary Health Centers in Dubai, United Arab Emirates: A Retrospective Study.
Article in Cureus, 2024. 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
objectiveThe study aims to apply the Mentzer index to the population of all eligible pediatric patients presenting to primary healthcare centers (PHCs) in Dubai for the first year of life screening. Additionally, the study will estimate the prevalence of iron deficiency anemia (IDA) and β-thalassemia in children presenting to the PHCs and evaluate the importance of PHCs in screening children for IDA and β-thalassemia by comparing the results of this study to previous results.
methodsThe SALAMA system (electronic medical record system used in PHCs in Dubai) was used for collecting the data. Eligible patients' data, such as hemoglobin, mean corpuscular volume (MCV), and red blood cell (RBC) counts were collected and recorded. The Mentzer index was applied to patients and the index results were compared to the gold standard results extracted from the SALAMA system. The gold standard diagnosis for IDA used was the serum ferritin test and the gold standard diagnosis for β-thalassemia used in the study was hemoglobin electrophoresis.
resultsOut of the 75 eligible patients with low hemoglobin, 11 (14.6%) had low ferritin indicating IDA. Moreover, eight (10.6%) patients had abnormal hemoglobin electrophoresis indicating β-thalassemia. The Mentzer index was applied to the patients; 13 (17.3%) of them had a value less than 13 (β-thalassemia) and 6 (8%) had a value more than 13 (IDA). The sensitivity of the Menzter index in screening IDA and β-thalassemia is 99% and the specificity is 54.5%.
conclusionOur study found that the Mentzer's index is a reliable screening tool due to its high sensitivity; however, we suggest replicating the study with a larger sample size to get more clinically significant results.
