The role of serum zinc and selenium levels in etiology of febrile seizures.

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
backgroundFebrile seizures (FSs) are the most common form of childhood seizures. Determining the role of trace elements in the pathophysiology of FSs will contribute to the management of FSs by pediatricians. PURPOSE: This study aimed to investigate the effects of zinc and selenium on the nervous system and how they may influence the risk of FSs.
methodsIn this case-control study, there were 60 children in the simple FS group and 40 children in the complex FS group. The control groups comprised 50 children with fever but without seizures and 50 healthy children. Blood samples were collected within the first hour after FS.
resultsZinc and selenium levels were significantly lower in children with fever but without seizures versus healthy children (P<0.001). Serum zinc levels were lower in children with FSs (simple and complex FSs) than in healthy children (P<0.001) but higher than in children with fever but without seizures (P<0.001). Serum selenium levels in children with FSs (simple and complex) were lower than in healthy children but higher than in the children with fever but without seizures. However, these differences were not statistically significant (P>0.05).
conclusionSerum zinc levels are significantly decreased during infection, whereas they show a statistically significant increase within the first hour after FS activity. This indicates that the body secretes zinc during FSs to restore homeostasis, reduce oxidative stress, and increase the seizure threshold. Therefore, zinc supplementation during febrile periods may effectively prevent FSs in high-risk children.
