Plasma zinc and selenium levels in adult inpatients with Lassa fever in Nigeria: A case-controlled study.
Article in IJID regions, 2025. 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
Objectives: Lassa fever (LF), a viral hemorrhagic disease endemic to West Africa, carries a high mortality. Scanty studies indicate that micronutrients may play a role in immunity to LF. We performed a case-controlled study to evaluate plasma zinc and selenium levels in hospitalized patients with LF. Methods: A cross-sectional controlled study of adults with confirmed LF and healthy controls presenting to the Institute of Lassa Fever Research and Control, Irrua Specialist Teaching Hospital, Nigeria, was performed between January and April 2023. After informed consent, blood samples were obtained, and LF was confirmed using a real-time polymerase chain reaction assay. Plasma zinc and selenium levels in plasma were measured using the AA500 Atomic Absorption Spectrophotometer. Data analysis was performed using SPSS version 21.0, comparing zinc, selenium, urea, and blood urea nitrogen levels of patients with LF and healthy control patients. Results: We enrolled 124 patients: 64 patients with LF and 60 healthy controls. There was no difference in mean age (37.6 years vs 35.2 years, Conclusions: Significantly low levels of zinc and selenium were observed in patients with LF compared with healthy controls, suggesting a role in susceptibility and pathogenesis. Given that zinc and selenium are essential trace elements for optimal functioning of the immune system, they may play a role in improving management outcomes.
