US observational study examines prevalence of self-reported Long COVID in adults

An observational study examined the prevalence of adults in the United States who reported ever experiencing Long COVID. The study design, sample size, follow-up duration, and specific data collection methods were not reported. No intervention, exposure, or comparator groups were described.

The primary outcome was the prevalence of adults who reported ever experiencing Long COVID. The study did not report the prevalence rate, absolute numbers, effect sizes, confidence intervals, or p-values for this outcome. The direction of any findings and data on secondary outcomes were also not reported.

No information on safety, adverse events, tolerability, or study discontinuations was provided. The funding sources and potential conflicts of interest were not reported. The study did not describe specific limitations of its methodology.

Given the lack of reported prevalence data and key methodological details, this study provides limited evidence for clinical practice. The absence of specific numbers prevents assessment of Long COVID burden in this population. Clinicians should interpret these findings with caution due to the significant data gaps.
