Hidden burdens: The dual burden of subclinical iron deficiency and hemoglobinopathies in afro-descendant populations of Colombia's Pacific coast: A public health concern.

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: Iron deficiency and hemoglobinopathies significantly impact public health, affecting morbidity, mortality, and quality of life. Their prevalence and consequences vary across populations, with Afro-descendant communities being of particular interest due to unique genetic, socioeconomic, and cultural factors. Subclinical iron deficiency, may go unnoticed in these populations, contributing to adverse health outcomes. This study aimed to determine the presence of iron deficiency, anemia, and hemoglobinopathies in Afro-descendant Populations of Colombia's Pacific coast. Design and methods: This descriptive, cross-sectional study included 198 Afro-descendant adults, both men and women, recruited through convenience sampling from various healthcare centers in the Pacific region. All participants provided written informed consent prior to enrollment. Blood samples were analyzed for total hemoglobin, ferritin levels, and hemoglobin variants. Results: Only 18.1% of participants reported a previous anemia diagnosis. Low hemoglobin was found in 23.2% of participants, ferritin deficiency in 49%, and 33.8% presented subclinical iron deficiency (low ferritin with normal Hb). Hemoglobin variants were identified in 17% of participants: Hb AS 4.5%, Hb AC 3%, and HbSS 0.5%. Hemoglobin variants were significantly associated with low hemoglobin Conclusion: The high frequency of subclinical iron deficiency, anemia, and hemoglobinopathies in this population highlights the urgent need for strategies focusing on prevention, early diagnosis, genetic counseling, and comprehensive health management in Afro-descendant populations.
