Dynamic Thiol-Disulfide Homeostasis Post-COVID-19 Depends on Age, Gender, and Symptom Severity.

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
introductionIt has been indicated that the thiol-disulfide homeostasis plays a role in the pathogenesis of COVID-19 infection. We assessed the impact on the thiol-disulfide homeostasis at 15-day intervals until 60 days, implicated in the pathogenesis of COVID-19, and its clinical relevance in disease progression.
methodsIn this study, 43 COVID-19 patients (18 females and 25 males) were categorized based on symptom severity, age group, and body mass index. Serum samples were collected on days 15, 30, 45, and 60 after COVID-19 diagnosis. Thiol and disulfide parameters were measured in the collected serum samples using spectrophotometric methods.
resultsSerum thiol levels were higher in females and disulfide levels in males (p<0.05). Disulfide levels increased in those older on 15-day post-symptom onset (p<0.05). Serum native thiol levels were higher in patients with moderate and severe symptom severity (p<0.05) than in those with mild severity. The symptoms of chest pain, shortness of breath, loss of taste, and loss of appetite were negatively correlated with thiol levels (p<0.05).
conclusionsThis study suggested critical findings of higher disulfide levels in older age and men, even in the weeks after disease onset. This discovery is significant as it could pave the way for interventions to repair thiol-disulfide homeostasis, potentially transforming the treatment of this group. Moreover, native thiols can point to disease severity even weeks after the onset of symptoms.
