Clinical trial of the effects of postbiotic supplementation on inflammation, oxidative stress, and clinical outcomes in patients with CVA
The submitted full text contains only the Introduction section repeated three times — no quantitative data, effect direction, or confidence intervals can be extracted.

Context
Stroke triggers neuronal damage via oxidative stress and inflammation; post-stroke gut dysbiosis is associated with worse prognosis. Postbiotics (non-viable microbial components) offer immunomodulatory and antioxidant properties with greater stability than probiotics. This is presented as the first RCT evaluating postbiotics in stroke patients.
What the study showed
Methods, Results, and Discussion sections were not provided — only the Introduction was submitted, repeated verbatim three times. No quantitative data, p-values, effect sizes, or confidence intervals can be extracted. Full critical appraisal is not feasible.
How it was done
Described as a clinical trial published in Scientific Reports (October 2024). Study design, sample size, duration, inclusion/exclusion criteria, randomization, blinding, and intervention protocol are unavailable from the provided text.
Effect magnitude
No effect size extractable. No 95% CI available. Quantitative estimation is impossible with the provided text.
Limitations
RoB 2 assessment (standard tool for RCTs) cannot be applied without complete Methods and Results sections. The submitted text consists solely of the Introduction, replicated across all three requested sections. Selection, performance, detection, and attrition biases cannot be evaluated.
In clinical practice
No clinical recommendation can be derived from the available text alone. Clinicians should not modify practice based on this incomplete submission. Full data must be reviewed before any interpretation.
What is still missing
Access to the complete manuscript with Methods, Results, and Discussion is essential. Multicenter RCTs with ≥90-day follow-up, validated functional outcomes (e.g., modified Rankin Scale), and longitudinal microbiome profiling are the field's next research priorities.
