Serum ferritin in Yemeni patients with sickle cell anemia: Association with sociodemographic factors and hematological profiles.
Article in PloS one, 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
backgroundIron overload remains a critical complication secondary to transfusional therapy and altered iron metabolism in patients with sickle cell anemia (SCA). Hyperferritinemia often serves as a surrogate marker for iron overload; however, as an acute-phase reactant, it may be elevated due to chronic inflammation, infection, or liver disease, potentially overestimating true iron stores. In Yemen, the burden of SCA is high, yet local data on the frequency of hyperferritinemia are scarce. This study aimed to describe the distribution of serum ferritin (SF) levels and the proportion of SCA patients with hyperferritinemia among adolescents and young adults attending the YSTH clinic in Sana'a, and to explore associations with hematological, and sociodemographic parameters.
methodsA prospective cross-sectional study was conducted between June and December 2024, involving 80 participants (aged ≥ 15 years). The data were analyzed using SPSS version 26. Due to the non-normal distribution and high dispersion of SF, the Median (IQR) and Spearman correlation were utilized. Bivariate analysis calculated crude odds ratio at (95% CI) to identify predictor of elevated SF. Statistical power was limited by the sample size (N = 80) to detect weak associations.
resultsThe study enrolled 80 SCA patients with a mean (±SD) age of 18.5 (±3.69) years, of whom 65% were males and 35% were females. The median (IQR) SF level was 1645 ng/mL (414-3525), with values ranging from 77.1 to 4500.0 ng/mL. Approximately 85% of patients exhibited elevated SF level (≥300 ng/mL). While red cell indices did not significantly predict the risk of hyperferritinemia, a significant positive correlation was observed between SF levels and white blood cell count (p = 0.03), suggesting a possible link with the inflammatory state. No significant associations were found between sociodemographic factors and high SF levels.
conclusionA high prevalence (85%) of hyperferritinemia (≥ 300 ng/mL) was observed among SCA patients attending the YSTH in Sana'a, Yemen, suggesting probable iron overload. While findings support routine SF screening but highlight the need for future studies incorporating inflammatory markers (e.g., CRP) and systematic transfusion histories to definitively quantify the iron overload burden in this population.
